[random] fanned base plate

Anyone thought about raising the ouya with a fanned base mount of some kind, and creating some vents in the top to make the case a little wind tunnel. I mean it's great the processor has a heat sink and fan, but all that heat still needs an escape. anyone already working on something like this, or have thoughts on it?

Hey bwild... I just received my Ouya a few days ago and this was one of the many initial issues which i've noticed, especially when you launch a game and leave it sitting at the title screen for about 15 minutes. It heats up pretty well and if the ambient temp is 25c or higher then the little thing struggles to cool itself.
After opening mine up, i can see several points which cause me concern heat wise, and obviously the long term issues are potentially reducing the lifespan of the device as a whole.
1. Due to the size of the device internally, and the amount of air that the small fan can shift per minute and the lack of escape points for heat, the device warms up pretty quick as essentially the small cooler is just reusing warm air internally to try and cool the heatsink. There is no heat shielding on the inside of the case to isolate the board from the surrounding case so the entire device heats up but the only effective cooling part is the small heatsink. Its a REALLY bad design.
2. The mobo inside is mounted on its side, this forces the fan and heatsink to fire out warm air towards the vents at the top and the bottom of the case, well at least im sure they are 'Vents' . Im quite sure that this kind of heat build up and pressure makes it almost impossible to draw any kind of reasonably cooler air from the outside, inside. Any air being drawn in is already warm before it even hits the cooler. My Ouya does get noticeably warmer underneath the device but i also believe that this is due to the 4 small metal weights which sit right at the bottom of the case heating up as warm air is expelled downward from the heatsink... I'm thinking of removing these as they are acting as a small heater with cool air trying to enter the underside of the case. But i can test and let you know if theres any difference.
3. The unique shape of the Ouya doesnt help either i believe... Warm air being expelled downwards towards the bottom of the case, will naturally try and rise and move up the curved side of the case internally and then get drawn in by the cooler again, im no expert when it comes to these types of things but im pretty sure thats whats happening.
4. I've replaced the standard 40mm fan with an Akasa 40mm fan with slightly higher airflow rating (and a little more noise), Not sure if this again helps much due to the design but it should help to at least cool the device a little quicker once your return to the Ouya dashboard.
5. Something else that i noticed was that the heatsink is actually spread across what looks like the GPU and (What looks like) Memory Modules, i cant confirm this as it was a side on look and havent removed the heatsink (Yet). Again i noticed that the GPU sits on one half of the heatsink (the side which is closed to the bottom of the case actually) so im wandering if this heatsink is doing anything at all I'll see about removing this at some point and probably putting a highly polished copper shim on it with some better heat compound, silver or ceramic and see if this helps.
6. The underside of the motherboard, has no cooling or anything on there despite a memory module being present on the back but i dont think that this will cause any issues.
So will all of that in mind... i've set of to find a suitable cooler of some kind that wont require ear plugs or make the device levitate 2 inches from the surface its supposed to be sitting on.... Space is a real killer inside this so i think we are going to be limited to what can can do however i'll need to see if theres any way that i can change the airflow in the device to allow for cool air being drawn from underneath and the warm air being expelled from the top. Sounds simple but i dont think its going to be anything easy... Just by looking at the Ouya, i had the crazy idea of trying to mount a 80mm fan (Low Profile if such a thing exists) which has a low rpm which sits between the top of the case and the top lid where the power button is. There may be much pressure between the fan and top lid though so there would need to be some mods and see if i can get enough power.....
All of this sounds extreme for what it is but i hate warm devices
I came across this : http://www.ninjalane.com/reviews/motherboards/rampage3extreme/page4.aspx : which shows a small chipset cooler. This would allow you to mount is side ways with the fan obviously pointing towards the top of the case and flip the fan over so its draws air from underneath and out through the top. Its either something like that, or we start a watercooling ouya project LOL :highfive:
Well thats my 2c

I think the outside only gets warm because it metal if it were plastic no one would know.

Ok.... Quick test there after work.
Removed the lid, played Shadowgun for about 30 minutes. Fan kicked in a couple of times, but when the fan kicked in for a 3rd time, I exited back to the dashboard and the fan stopped immediately.
Console was slightly cold to touch and the heatsink was roughly a little warmer to the touch so I'd say between 40 and 45c at the most. :thumbup:
Compared to last nights epic slaughter session on Shadow gun, the fan remained on for approximately 10 minutes with no system usage, just sitting at the dashboard as it tried to desperately cool itself.

It's running a mobile cpu... won't it just throttle itself if it actually gets up to a dangerous temperature??
Sent from my Nexus 4 using Tapatalk 2

I agree mate yes... however i'm not sure if it does actually throttle itself? On an enclosed mobile i can see why thats required, on an open, air cooled device (albeit poorly) there wouldnt really be a requirement for throttling, unless they know it couldnt cool itself properly there any way we know for sure?
That aside though, the device will still take some time to cool down even when throttled as it will still generate heat
Personally if i am playing a game at 1080p, i'd rather not have to suffer from reduced quality when the device throttles due to poor design!
I did notice as well initially when i had a really good session on Shadowgun, that the frame rate on a 1080 monitor was dropping below 30fps and the textures didnt quite look as crisp, so maybe it does throttle. If thats the case, i'll play it with the lid off until i can stop it from overheating and lowering the core frequencies :good: I'll make this a little project and see how cold i can get it to run.
If i make any changes that i think are working, i'll post a few pics :highfive:

Im going to picking up a mini-itx case so i can not only rectify the cooling issue when running my roms , but also to permanantly install a usb hub and hard drive internally. I am growing accustomed to using this for media too, so a hard drive is a must. I will post some pictures and video as I move along with it.

played through shadow gun and the left over and the system stayed cool to the touch the fan did come on a few times

I stripped mine down again tonight and had a closer look at the PCB. Looks like the heatsink, which is soldered on, isnt flush. It rises slightly at the end where the CPU/GPU is so that's maybe why mines is a little warm. I can apply a little pressure to the high end and it does drop 1 maybe 2mm. So maybe my heatsink isn't as effective as it should be.

Here is the simple rigging I came up with.
A 60mm case fan with some allen bolts for legs. Plugged into the ouya usb (I still need to split it so I don't loose a slot.)
The fan blows up through the bottom vents, I do intend to cut a couple extra slits in the top too.

Thingiverse has the plans for the ouya and others have likely moded it for better air flow if you have a 3D printer.

This is what I'd ultimately want to do I have a design in my head for incorporating the fan inside the bottom of the case raising the board by the equivalent height and adding in just a spacer with additional venting, between the case and top cover.

That's awesome mate!! :good: Do you get a noticeable difference with that fan?

it is noticeably cooler to the touch. I'll try to measure it somehow and update when I get a chance.

So I picked up a dead sega dream cast at the flea market, got it home, gutted it, cleaned, and got most of it done. I was able to convert the sega push button power switch to a momentary and soldered the leads to the ouya main board. I hot glued the connection afterwords so it will stay (the power pins are tiny). I added two USB ports to the front and rear using a USB hub. I also mounted an hdmi coupler and m type power connector on the rear. I made a jumper cable to hook up power internally. I'm also looking into wiring up the stock dream cast cooling fan to use as side exhaust. I will update when i get the cooling sorted out. The point of doing this was to increase airflow in the case and make a more compact package for all of devices.

Pretty cool, I considered doing this as well with a dreamcast, but won't have a chance till I buy another OUYA specifically to mod. Looking at it, I have 2 concerns. Your USB hub is almost wasted, isn't it? I mean the majority of USB ports are inside the case, or am I missing something? What about heat? With the OUYA in the middle, close to the top, wont it cause more heat? or do you think the second fan will fix that?
Have you thought about anything to do with the lid/cd area?

I wanted the majority of the USB ports internal for use with the front USB ports and to add internal storage. You are correct about the pcb location and I'm going to make small vents above the fan inside the cd area for air intake. As it sits now heat isn't in issue yet. I mounted the pcb near the stock fan location so once I have that working it can pull air out more efficiently. Using a dream cast was great, I wish I did this in my spare Nintendo 64, but I didn't have the security tool yet (ordered last night). The n64 cartridge slot makes an amazing air intake, I will more than likely do it when I pick up another ouya ?.

So I got around to wiring up the stock dream cast fan to maximize air flow and moved the led from the pcb to the lid of the console so now the light can be seen.

The first picture is with the cd tray open to show the vents I had to create since the CPU fan sits below. In both pics you can see the light now works. I ordered right angle USB adapters last night and will update when they are installed.

...and so nothing falls into the system or the fan ...

Experimenting w/ Hardware Mod

I was inspired by this thread http://forum.xda-developers.com/nexus-4/general/hardmod-nexus-4-investigating-thermal-t2144652 and decided to do some experimenting.
My phone was idling at about 53 degrees with screen on at 50% brightness w/ auto brightness off, ambient temperature of 70 degrees farenheit.
I ran two Antutu benchmarks from idle temperature. Results were 31990 and 31555 and a max temp of 77 degrees.
I then ran two Qualcomm benchmarks with scores of 1860 and 1855 with the temperature topping off at 66 degrees.
I disassembled my phone and removed the main board. I added a small drop of Artic Silver thermal compound to the processor and reassembled.
Results after adding thermal compound. Phone idles about 9 degrees cooler, at about 44 degrees. Max temp while running Antutu benchmark is down to 71 degrees with scores of 35356 and 34856. Results for Qualcomm benchmark after thermal compound, max temp of 60 degrees and scores of 1880 and 1875.
I may clean up this post later with pictures etc but I did this on a whim. This whole process only took about 25 minutes. Phone comes apart extremely easy and with excellent results so far. If you take the plunge and open it up, I noticed that one of the screws at the volume rocker assembly is longer than the other, be careful of this when reinstalling.

I was considering doing a similar thing using a thermal pad. I assume the Arctic Silver was applied under the metal shield?

Damn,
why I didn't ask for this when my G3 got repaired

The processor is exposed in the middle of the metal shield, like at 3:18 of this disassembly video. https://www.youtube.com/watch?v=rRXzRQ69264
You might be better off using a thermal pad, as there is quite a gap to fill with thermal compound. I think ideally I should use a pad or a copper shim like in the thread I posted in OP.

Yes thats the shield I mean. I assume it just pops off, its not soldered to the mainboard? On the G3 the CPU faces away from the LCD so heat transfer to the LCD (as is likely on the N4) isnt a problem for us.
I wonder if a pad under the shield and a pad over the shield would be possible. The buttons are over it, but it might just fit.

I'm not sure how the shield comes off, I didn't pay much attention to it. I applied compound to the processor without having to remove the shield.

CPU does indeed face the display as on the N4. I think you're mistaking the NAND for the processor?
When stress testing for 10 minutes the display definitely got quite warm but I don't think I will be pushing it that hard too often.

The CPU and RAM and stacked together on the G3 and are underneath a thin metal shield. It has to come off to access the it.
EDIT: ah I see I read the images wrong, the CPU does face the LCD.. Hmm.

You were probably looking at the same teardown I was. It's confusing the way it's posted on there. I doubt I can damage the display but if I do I guess I'll accept the couple hundred loss for having to tinker with things haha. Temperature as I type this is 42 degrees. Solid ten degrees lower than 'normal'

i'm interested in doing this mod. can you share your pictures? because none of the teardown show the processor.

How the heck if your phone so cool?
Mine is like 30 degrees Celsius (86F) when just browsing the net, goes up to 40 degrees Celsius (104F) :/

Do you have an estimate of how much of a "gap" has to be filled? I'm planning to try this with either paste or coollaboratories liquid ultra i still have lying around.

I didnt take pictures, sorry. The processor is on the back side of the board, facing the display. It's in the middle of a metal housing, you can't miss it. If I teardown again and switch to a thermal pad, which I think is more ideal, I'll be sure to take some.

Hmm, I'd say about a .1mm gap. I'd really recommend some sort of copper or aluminum shim with compound on both sides of it. Or a thermal pad. Thermal compound isn't meant to fill this kind of gap, although it does work.

No problem dude. Thanks for the tips. But do you think this mod can compromise the LCD, somehow more heat will be transfered to the LCD and then could cause some problem...

It could cause a lcd issue. I turned off thermal throttling then ran the cpu at max for 10 mins with a stress test. The upper part of the lcd where the processor is does get quite warm. When playing asphalt it gets warm but nothing crazy. My opinion is it will be fine, but use this mod at your own risk of course.

Nice. Let us know how it goes

Finally done with the mod. After checking taking the phone apart i feel the best option to go is a 0.5mm thermal pad/copper shim. The added thickness should put a little more pressure on the SoC for better heat transfer.
Can report the same 9C difference on idle from 54 to 52.
Antutu scores:
Before: 31438
After: 36099
Load temp max from 73 to 64.
Strangely everything feels smoother but could just be bias on my end.

15mmx15mmx0.3-5-8-1, think I'm going to try just putting a 0.5mm shim on the CPU with some paste, none on the screen side, I don't want the area of the screen there getting too hot - the copper itself should act as a good heatsink

Why? The only thing this device needs is 4 gb RAM mod. Nothing else.

because putting a copper chim on the back of the CPU that overheats is a good temporary fix until I can organize shipping my phone to china? I'm talking to [email protected] in PM about it but it's hard because his english isn't very good. he says $200 without shipping for 128gb internal storage upgrade and 2gb-4gb ram upgrade.

Let me know how that goes, as I would be very interested. I love the 5x, but there are a number of limitations that are starting to peek out.
16GB storage
2GB ram
CPU is fast enough for me, but overheats and throttles
Battery lasts ~4 hours SOT
If I could upgrade to 128GB, 4GB, cool the CPU with a copper shim and some modding, and then swap my old battery for an LG G2 3,000 mah one, I could see myself using this phone for several more years!
Or at least until Android P comes out, and I get upgrade envy.

I just finished this in the morning. Initially I got the idea from here: youtu.be/mV8_hsua4vo.
Used a 1mm thick, 15 x 15 mm copper pad that I bought locally, I couldn't get a 0.8mm one and waiting for an order from Aliexpress for such a tiny item is not my thing since our national post is a mess and it adds up like a week to an already huge delivery time.
So I sanded down the 1mm one to about probably 0.8, just enough so the board is not floating on it and the contacts for the ear piece are fine.
Removed the factory yellow pad, cut the thin foil off of the metal shield, slammed some DeepCool thermal compound that I had laying around and pieced it back together.
All I can tell you is that I can't get the CPU temp past 52°C. Tried all the trending benchmarks on the PlayStore, max brightness, streaming Play Music over bluetooth to my headphones, you name it.
That 52 is peak, doesn't stay there, at idle it ends up around 30 to 32 and some casual browsing with mid brightness goes up to around 40.
So the most is runs at when gaming or doing heavy tasks is between 40 and 50. Which is a massive improvement over stock temperatures and even better than the thermal config that I used to run (see bellow).
Worth mentioning that I'm running the extremeV4 thermal config, throttling temp at 51, EX Kernel with Heimdall_5x_v4 profile for the interactive governor.
The screen is NOT getting too hot, in fact it used to get hotter before, without the copper pad.
Sorry I don't have any photos, but I don't have another camera, just an old GoPro H3+B - useless.

Tried this too. Didn't seem to do much though.. Tried this test and CPU didn't reach even close to 40 degrees Celsius. Weird thing was that the two faster cores quickly went offline after starting the test though..
EDIT: I used a 1 mm thick thermal pad but now notice a blue spot around the cpu. I can also see a curvature in the screen under the right lighting. Maybe the thermal pad is too thick? I figured a 1 mm pad could be squished down to 0.8 mm if it would be too thick..

I just saved mine via fastboot with a modified img but having two disabled cores bothers me. I thought about replacing the motherboard or upgrading/replacing the two cores to a new one with 4gb ram and then adding the heat sink. Do you guys think it's worth it or should I just leave it be

Hi,
i made the mod a few days ago. i used a 0,8mm 15 x 15 mm copper pad.
It works great.
But today i used gps the first time since the mod and got a big problem. I was driving with maps und a had a few seconds gps then searching for gps then a few seconds gps and searching again.
Anyone alse noticed some problems with gps after this mod?
Or any ideas what could happend?

I had the same issue with GPS, seems like only done encounter the issue. I just had to get a new thermal pad. Found some Arctic thermal pad that is .5mm thick and used that.
Here is a post of mine in another thread

ok thank you. seems like not everyone got this problem.
i will try to press the backcover a bit on the mainboard next time.
if that doesnt help i try with the thermal pad or maybe a thinner copper pad.
are your temps better with the pad than original?

I couldn't use the copper pad at all, and it wasn't a clearance issue. I tried a thinner shim and I had the same issue. Send like there is some sensor or something that gets blocked by using a metal shim. I used CPU throttling test and it said performance improved by about 10 percent or so. But in real world it's a bit better but essentially couldn't use the copper pad.

I have the copper pad in there and I use Strava and Google Maps almost every day but never had a GPS problem.
I still believe you are encountering a problem with the antennas' pins not making contact with the board.
There just can't be any shielding or any problem from the copper pad, since the whole back of the display is a big chunk of aluminum that would mess the GPS even more if that would be the problem.

makes sense... but than an 0.8mm copper shim seems to be to thick.
i dont used to much thermal paste...
do you know which of the pins on the backcover are for gps-antenna?
maybe i can try to improve the contact.
if that doenst work i will try an thermal pad.

Cool!

Paste
Is it necessary to use thermal paste, or can I use glue?

I just took out the copper pad because I lost all gps signal and after troubleshooting every other possible cause, I went with the "rumour" that the pad is causing interference. And oh man, it does!
I have no idea how my gps worked for like 8 months, since I got the mod in. Still, Strava was losing signal here and there, generating zig-zag lines, but I blamed it on the app.
Now everything is fine, I get signal from at least 6 fixed satellites and Strava is super stable.
I guess I'm back in line to get the bootloop now, the SoC is back running in the 70s and 80s C.
So I think you can forget about this mod unless you don't care about proper gps signal.

Nexus 5x 32GB 4GB ram + 3400mAh battery + heatsink mod

Needed an inexpensive spare phone. Picked up a Nexus 5x 16GB for less than USD50, with problems (Unable to turn on, only red LED when trying to charge) so starting a project to revive it.
Stumbled across this thread.
Bit the bullet and bought the oudini UNLOCKED H791 32GB Mainboard with the 4GB RAM and a Da Da Xiong 3400mAh Battery to go with it.
Planning to do the copper heatsink mod too.
Was thinking of expanding on the idea of the copper heatsink mod with this Experimental "home-made" modding for heat dissipation mod. Aluminum foil was used along with liquid metal thermal compound in that thread. Not a good idea as liquid metal with aluminum is a recipe for disaster. I was thinking of using copper foil instead. Haven't decided on whether to use thermal paste or liquid metal. Also thinking of creating a bigger surface footprint for the "heat dissipation pipe" like the attached picture.
Your thoughts?
Will update once all parts arrive and I begin assembling. :fingers-crossed:

Good luck with that. Sounds like fun.
With that mainboard, is there any guarantee it won't start bootlooping a few months down the road?

Good to see somebody else dumping money into such a hobby
Aside from my daily driver 5X, I have another one now at the shop for a reballing job - kind of a long story, outcome still unknown
I don't think that whole 'heat pipe' situation is needed, you are going to be fine just with the copper pad.
I've been running it for a few days now and honestly it's more than enough. You won't get anymore performance out of this chip unless you go sub zero cooling or something.
Seriously, having it run at 30 to 40°C on daily normal usage and 40 to 50 in games or other intensive tasks is just fine.
Thermal throttling is also kept to a minimum, especially with the non-stock thermal configs.
That battery capacity is jank, you can't physically fit that much juice into that space.
The best battery you can get your hands on is a LG *allegedly* original unit from Amazon sold directly by LG. Other than that, you are always going to end up with some knock off that gives you, at best, the same battery life as a 3 year old original one.
Good luck with all this then.
But you'll probably ditch it all in a year's time for a Pixel, when you'll want that fresh Android. That's going to be my story, anyway.

I guess there are no guarantees... My understanding is, this bootloop is caused by hardware problem with solder connections between the board, RAM and CPU. The RAM is packed with the CPU together on the top.
This main board has had a new RAM/CPU soldered on. So unless it was a shoddy job, it should all work. Now, under heavy load, heat builds, and when it gets too hot, there is a possibility of the solder connections giving problems again. Which is why I thought of doing the copper heatsink mods to reduce the chances of it happening. Also, with the 4GB of RAM, I am hoping it will have less stress on both CPU and RAM, which in turn will generate less heat, thus reducing the chances of the problems with the solder connections.
All this is just theoretical. I guess I have to build it and see how it goes. :fingers-crossed:

I don’t really game on phones but where I live, temperatures and humidity are quite high. Not looking for crazy performance, just hoping the phone stays cool and will last a while.
As for that battery, we’ll see. No harm trying after all. A guy on reddit bought one and said it does last longer than the original. If it sucks, I’ll just revert back to the original one.
This is just a small hobby/project, who knows how long I’ll use it. I actually already have a Pixel 2 XL. As I’ve mentioned, this is just a spare.

I also bought one of the 4GB boards (two actually) and replaced a dead N5X from ebay with the upgraded one. Works flawlessly, will post screenshots of the system info of 4GB RAM soon when I have my phone sorted.
I'm curious about that battery though - is it legit 3400MaH?
This is the 4GB board I bought, same as you. My first two didn't make it past chinese customs but he sent another two and they made it fine. https://www.aliexpress.com/item/oud...for-LG-H791-32GB-Motherboard/32846103543.html

At the moment, no one reported bootloops on Nexus 5X with 4GB Ram. We will see in the future.

4GB board installed, just installing apps and setting it up etc. Feels snappier anyway. When installing ElementalX kernel, I set the read-ahead buffer from 512kb to 1024kb to adjust for the increased RAM.

Soon I will order one Motherboard. If my 5X will have bootloop again.

No idea but on the sellers ad, they say they use a EBC-A10H machine to test their batteries for the desired result. Also, there are a couple of brands besides the Da Da Xiong one that I bought. There's HSABAT, LOSONCOER and IBITION.
On reddit k3v1ng1994 says ;-
"Just wanted to update you on the extended battery.
I finally had it delivered a couple of days ago. I can confirm that the battery does so far last longer than the OEM battery- I just don't know exactly how much by.
The biggest issue is the battery has thrown my phone out of calibration. No longer can I see what battery percent I'm on (it always stays on 50%), and the screen on time isn't resetting when I put my phone on charge. I've tried many ways to try and recalibrate the battery, with no luck.
I would say it's not worth getting for this very reason. I'd rather be able to tell how much battery I have left, rather than have a longer battery life. But you might be interested in giving it a go, especially if you're rooted since you can take additional measures to calibrate the battery."

I guess there is an issue with calibration but I think should be an easy fix with a flash of stock images (or factory wipe) and batterystats.bin will be removed in /data/system... Should be calibrated after that. Not sure which brand he bought though. Who knows. Will try and see how it goes.

Got a notification, my items have been shipped!
Main board should arrive by the 2018-03-18 but the battery says 2018-04-08 . I've ordered stuff from China recently and they usually arrive before their estimates. Hopefully they get shipped out of the country before their Chinese New Year holidays. Then it's up to my country to deliver the goods.
Took apart the phone today and tried the "heating" method fix but it didn't work. I got as far as getting "Google" to appear on the screen then it gets stuck there.
Anyway, looking at the heatsink/"heat pipe" mods, I'll probably stick to thermal paste instead of liquid metal. Liquid metal is corrosive. Even with copper the metal ions will migrate into the copper metal, gradually creating a copper-gallium alloy that is grey-silverish in color. Which is why people think it's drying up. It's actually the copper absorbing the liquid metal.
Looking at what PC CPU heatsink are like these days, the contact point is usually copper, followed by aluminum fins for faster heat dissipation. Why not just follow that recipe. :silly:
So, looks like the copper foil I ordered won't be of any use now :laugh:.

Really don't think a heatsink mod is needed, in my old phone I used a 0.1mm(or 0.2mm I forgot) copper shim over where the CPU is, stuck it on with thermal paste, didn't make much difference in cpu temp.

A .1 or .2 mm shim won't indeed change anything, it's way too thin for the chip to be in contact with the chassis. Especially if you don't remove the factory yellow pad and the thin foil from the chip shield.
With a .8 or .9 mm copper pad (can't tell for sure, I sanded down a 1mm pad) I can guarantee that you'll notice the temp difference, the throttling is almost gone.
It also depends on what thermal paste you use and how much of it.
Also to everybody wondering why the bootloop issue occures, here's a few things:
The 808 and 810 were the first x64 chips Qualcomm came up with as a response to Apple's. So you can imagine they aren't exactly well thought out, especially in the long run. You can do a bit of research to see how they just janked together some ARM cortexes, slammed a GPU in there and called it a day. Samsung even ditched the 810 from the S6 and used in-house silicon - I think we can safely assume Samsung knows its hw game.
The stock thermal config and kernel are absolute garbage and don't help at all with the thermal throttling that keeps the little cluster pinned at 1440Mhz and the big one off, anytime the package is above 46°C - that's most of the time. Now you tell me how easy that is on the hw.
These design flaws coupled with possibly bad soldering led to our problems. Even though it's hard to imagine that so many boards made it out of the production line with bad soldering since that's a mostly automated and very tidy job, leaving little to mistake.

I don't want to go OT, but understanding some things may help "solve" the heat / bootloop problem in non-bootlooping N5X. In stock kernel, through ExKernelManager, I've seen CPU at 96º C when taking photos with HDR+ With Jolla kernel and the big off, CPU hardly reaches 60º C. If soldering is not "the problem", an "accurate" kernel configuration will be enough to avoid the bootloop? Sorry if I misunderstood your explanation or if I ask something stupid. I know nothing about this, but I would love to learn something. Thanks!

All I'm saying is pure speculation, the web is filled with people talking bs about 808 and 810.
Also, Qualcomm, LG or Google never settled this with actual honest facts.
Another fact is that some Huawei made Nexus 6P devices bootlooped as well, so you can see how one could easily think that the root problem is the architecture itself of that generation of SoCs.
On the other hand, I can make an 'educated guess' about how a cooler running package prolongs its life and puts less stress on the 'allegedly' weak soldering.
So I think it's safe to assume that running a custom kernel and thermal config, along with other tweaks like the heatsink, will dramatically increase the life of your 5X.

Hello friends first forgive the translator's mistakes. I already knew this topic before but did not know that the motherboard had already been sold already modified.
My thanks to @LeonF for providing the link of the sale of the motherboard with 4GB of RAM.
I already have a functional 5x nexus, but I bought another today with the burned motherboard per US $40.00. Then I bought the motherboard per US $132.05 5% off.
Unfortunately I live in Brazil, the customs (IRS) here are horrible, it will certainly take up to 70 days for me to receive the product, as soon as arrive i come to post my opinion here... on a battery 3400mAh do not think it's good.

I have noticed with my 4gig ram board, my battery usage is really good. same battery. ordered two of those 3400mah ones though, but somehow more ram = better battery time

Copper shims arrived today. They're 15 x 15 x 0.8 mm. Took the phone apart, did a mock of the copper shim then cleaned off the yellow thermal pad...

So @Mortihead found a service that will replace your emmc chip to 32GB, 64GB or 128GB and mentioned I should try.

I got in touch with them and found out (as best as I can understand the WeChat translator) that the 128GB chips have been out of stock but they still have the 64GB ones and it will cost RMB280 to do it.
I found this chart from @ikfe from this thread of the part numbers...

Sure, but my idea is not an occasional adaptater but a real memory extend like this thread : http://forum.xda-developers.com/google-nexus-5/help/nexus-5-64gb-t3350533
I'm confused with 2 ideas :
-Add an SDCard slot (can be cool)
-Extend memory to 64 or 128gb (my advice SDCard still better)
On the iFixit Teardown guide, it says it's a Toshiba THGBMFG7C2LBAIL (16gb variant) chip.
And in the Toshiba catalog, like u can see downside, all chips seems to be the same type (P-WFBGA153).
The problem is the size of the chip. Upgrade can be easily done to 32GB (N5X Variant), or to 64 and 128 gb, up to 0,4mm difference.
Searched a bit on the web and finded some chips:
64GB Variant:

http://www.alibaba.com/trade/search?fsb=y&IndexArea=product_en&CatId=&SearchText=THGBMHT0C8LBAIG (Ask seller)
The only problem i see is like i said above, the chip size grew up to 0,4mm, so is it possible to do it without get an curved nexus?
Any ideas where and how is possible to put an SD Reader?

Searched for the 128GB chips and found this for USD$35. I can go as far as fitting the new 128GB chip but I have no idea how to proceed after that. Reading the thread about @KApetz2 and how he fitted a 64GB eMMC to his Nexus 5 you have to fix the partition tables to support the larger capacity storage or it wouldn’t recognize the upgrade. If someone can point me in the right direction, I might try it out.

HD8 Cooling Mods + overclock?

tablet is stock other than having the playstore.
Not sure what rom is best/least buggy, open to suggestions.
i'd like to overclock the tablet. i know what gets hot, and could slap a laptop heatsink to it.
Could someone show pics pointing out where the ram,cpu/gpu are?
far as i've gathered they are under the second box from the left, on the back.
current rough idea.
On whatever rom i'm using, tests prior and after thermals along the way of overclocks and mods.
Pop the metal boxes open or simply remove them from the back, where the hot bits are.
add a laptop fin heatsink maybe with heatpipes (depending on how many fin stacks i'll put on) to all the parts that get warm
heat the plastic case and put it on, form the plastic around the heatsink, then run some air slits so it can breath fresh cool air.
Or has anyone done anything like this?
Feels like their stock OS is too bloated, not even sure an overclock is needed with a good rom.
but, i want to do it anyways, so.
if you're assisting, i could use a detailed guide on how to get a bootloader, or w/e you guys do to get all the unlocks and goodies on your stuff.
tried reading a few and couldn't figure much out.

What your device you're referring.
You can use cooling fan without PWM (pulse width modulation) wire.

fire hd 8 2019.
i've had it open, but the hot bits are encased in metal boxes. i'd have to look but i think the tops just pop off, or the sides solder off.
basically i want to get more performance, it's pretty slow, even fresh out the box.

You won't get much more out of the chipset. It's not about simply mitigating heat and then cranking up the clock speed or voltage. There are so many architectural bottlenecks any gain in one area will be offset by bottlenecks or throttling in another. Good luck with your project.
