Why every kernel with overclocking support, lowers the frequency on its on mostly when is overheated?If I remove mdtermal or something forgot the name is it gonna fix this issue? Thanks.

because thats how google had lg make it. you can always disable thermal throttle if you want, itll still keep the 100C safety temp though. mdthermal is for battery temp throttle, and there is a seperate cpu thermal throttle. trinity kernel disables the battery temp throttle, but you have to disable cpu thermal throttle on your own.
So I disabled the DVFS feature which I heard was some kind of thermal control but now the phone is unbelievably hot after intensive gaming session. For example I played xcom for 30 minutes and the phone felt like frying and the battery went down from 86% to 48%. I didn't have any cpu monitor so I don't know what temperature it was on, but it felt very hot. Is this safe? I personally think it isn't and I will probably turn DVFS back on.
I have a n9005 device, running xnote v15 and lean kernel 2.5.1 with default settings.
From what I gathered, DVFS was Samsung's "cheat" to enable awesome scores in Antutu and other apps that measured how well the CPU, etc worked... Disabling DVFS should in actuality leave it cooler as the CPU's/other aren't being artificially throttled up to maximum...
Correct me if I'm wrong...

Isn't the dvfs stock kernel related?

No its TouchWiz system based. You can set it in Wanam Xposed.
It may sound like it's related with the kernel, but the kernel does not see what is being run on the device (especially only benchmarking tools) and then ramps up the device to perform better than expected.

So yeah, I'm still new for G2 and I found thermal throttling issues to be very bad. I enabled temperature property but it throttles on 70c and does it fast. I'm not a huge gamer but still would like to fix this. Is it possible to increase the limit or something? Talking about stock LG ROM.
Thanks.
I had this issue that on some games the fps start to be dragged down after 15, 20 min. I've instaled new custom kernel for thermal throttle due to cpu heating, but seems to be related to gpu, as the cpu stays constant at about the same speed. I have seen a fix for s4 on the web: to change a value in this file min_pwrlevel, though there is not on this os. If Anyone has an fix for gpu thermal please give advice. Cheers.

As we all know, the Snapdragon 810 processor in our OnePlus 2 phones is prone to overheat, especially during heavy tasks such as gaming. With the stock kernel (which probably most of you are using) this leads to the A57 cores being partially or fully shut down and the display - which generates additional heat - being dimmed in order for the phone to keep a healthy temperature (healthy for both its components and the hands that are holding it.) This, in turn, leads to lag when playing especially demanding games. Which in turn leads to a frustrated user.
With root access, it's possible to use custom kernels and/or custom thermal throttling profiles in order to (at least partially) circumvent these issues, by throttling the CPU frequency and/or limiting the number of active cores, using different schedulers and governors, and by applying thermal profiles that allow the phone to get hotter (in order to keep higher CPU frequencies for a longer duration).
Since I bought the OPT, I was playing a very power hungry game - Republique - which, at its highest graphics quality setting, pushes the phone to its limits. I quickly switched from the stock kernel to the Boeffla kernel and started experimenting with schedulers, governors, hotplugging settings, CPU/GPU frequencies and thermal profiles, but nothing I have done so far makes it possible to play the game for more than 15-20 minutes before some kind of throttling / heat control sets in and the game starts lagging.
I tried limiting both CPU clusters to only 2 cores while maintaining higher frequencies, I tried throttling the frequencies and keeping all 8 cores active, and I tried all kinds of solutions in-between with anything from 4-8 cores active and frequencies anywhere between 60% and 100%. I also tried the various thermal profiles that the kernel offers. But whatever I did, the game was either lagging right from the start, or running smoothly for about 15 minutes before the screen was dimmed and the CPU was throttled, leading to a laggy experience.
So my question is, what do you guys do to keep the OnePlus 2 from overheating during gaming, while at the same time maintaining a lag-free experience? I don't seem to get anywhere with anything I try, so I'd be extremely grateful for some useful input.

All the phones throttle while gaming. I use thermal extreme with boeffla kernel. And use 2 a53 at 1,3ghz and 2-4 a57 at 1,4ghz and I modified the throttle file and it underclock to 1,2ghz when it gets hot but it doesn't happen if you don't play longer than 30minutes and it doesn't lag either. You can leave stock settings but if course it will get hot quicker. Also with thermal hotplugged or something like that, I used it all cores online all the time at full speed and it doesn't throttle for a long time, so I don't know what overheating are you talking about. My nexus 5 throttle faster and disable 2 of 4 cores and leave the other 2 at half speed, and our processor overheats?. Oneplus throttle the device a lot because of the rumors, fortunately we can change that. Try what I said, cheers.

Thanks for the tip with thermal extreme! The implementation in the latest Boeffla kernel v1.1 beta1 seem to do a very good job of not letting the phone get too hot while at the same time not throttling the CPU too much. Today, the performance was stable for almost 30 minutes of gaming, and when I checked the CPU stats I saw that all cores were still active (2x A53 + 4x A57), and only throttled to 960 MHz. This still delivered enough performance. (I started the game with both CPU clusters at 1.2 GHz, so this also seemed to help with keeping the phone at an acceptable temperature. I'm sure it would've gotten much hotter much quicker at higher CPU frequencies.)
I have to admit though, I was playing inside in an unlit room and thus the screen wasn't at max. brightness. We'll see how it will perform during my next work break when I have to make the screen much brighter.

Does it throttle to 960mhz? for me never reach 1,2ghz. Playing real Racing for 30min it stays at 1,2ghz. And with thermal hotplugged (all cores enabled, all at stock freq gpu too) it doesnt throttle for 30 min, gpu only sometimes to 510mhz, i played 30 minutes and it didnt throttle, i dont know when it was going to throttle because i stop playing. But also, gaming with all cores and no throttling eats the battery.

I guess it throttled to 960 MHz because the game I'm currently playing (République) is pretty resource hungry.
