The Common Helios 300 Power and thermal limit problems AGAIN!!

lithium

I bought a helios 300 that has a i7-8750h and gtx1060 2 month ago and I have tried everything to bring down temps while preserving performance but it just won't work,  while gaming the cpu reaches 95 C which level up the whole package and the gpu specifically to the sam temp and then the gpu begin to produces fps drops. I tried undervoltting the cpu with both xtu and throttlestop from -60 to -160 and didn't work, I tried matching the turbo boost short and max tdp to 45 watts and didn't work either. the Only thing that seems to bring down the temps to around the 80s is to disable intel turbo boost but it reduces the performance significantly.
here is my throttlestop settings on game and performance profiles



undervoltting here by -140 and -135 respectively in both cpu core and cache in addtion to -50 in intel gpu and keeping turbo limit on 3.4 in the game profile and keeping short and long turbo boost power at 45, both produced the same following benchmark on AC Origins:

and here is the temps and core clock speed while benchmarking:

the undervolting does help stopping the fps drops but the temps are really HIGH and I guess it will run much better if the cpu doesn't throttle on power or temps, the performance drops by 8 full frames in the Average when benchmarking while truing off turbo boost. the problem is really bugging me and it makes me frustrated knowing that it can run better temps and performance. my power brick is capable of feeding this monster more than enough and yet it struggles to sustain a 45 watt power usage for the cpu, also mu ram sticks are dual channel which apparently can affect the temps as I so In one video

Sounds like the heat sinks need to be repasted with a quality thermal compound like Arctic MX-4. But before trying this, you might want to see what happens if the power plan is simply set to balanced instead of performance. Jack E/NJ

I set the power plan to balanced and adjusted the max performance state to 80% and the min to 0%, lowered the turbo boost speed further to 2.8 ghz, undervolted to -145 on core, cashe and intel gpu, lowered the maximum tdp to 40 both on short and long boost and it seems that now it's better the average fps crenked up to the 70s and the temps are around 80s for both the gpu and cpu thanks for the reply hope any one tries these setting to confirm it's the idle ones.

Are you on windows 1809?

no I'm currently running the 1803 build, why ?

1803 its the worst of them all best its 1703 but 1809 its not bad either if you cant lower temps even after optimizing windows and undervolt your only option its to repaste with a good thermal paste like kryonaut or similar like @JackE stated above but dont do it yourself or you will void your warranty if you have seals or not allowed to do it contact your seller/shop or acer support to find out more about it send it for warranty if needed for repaste
