Acer Predator Helios 300, i7-8750H, GTX 1060 runs a bit hot?

Grawlix

When running Overwatch on low settings, my laptop still runs a bit hot.  I tried messing with the "Processor power management" settings, which seems to have helped with the overheating, but also led to some performance issues.

Laptop Specs:

* Acer Predator Helios 300 Gaming Laptop, 15.6in Full HD IPS Display

* Intel 6-Core i7-8750H

* GeForce GTX 1060 6GB DDR5 16GB DDR4

* 256GB NVMe SSD

* Model: PH315-5

Here's the results of my testing:

Test #1:

Processor Power Management Settings (plugged in):

* Minimum processor state: 100%

* System cooling policy: Active

* Maximum processor state: 100%

In-Game FPS: >144 fps consistently.

Max CPU Temp: 92 C

Max GPU Temp: 85 C

Test #2:

Processor Power Management Settings (plugged in):

* Minimum processor state: 0%

* System cooling policy: Active

* Maximum processor state: 99%

In-Game FPS: 120-140 fps (I'd like it to be over 144 to match the 144 HZ display)

Max CPU Temp: 72 C

Max GPU Temp: 78 C

Is there any way to achieve >144 fps without hitting the low 90s for CPU temp?  Or is that a fine CPU temperature (note that this was after only one game).

Unfortunately the Helios 300 does not have a great cooling system and both the cpu and gpu are linked together with the same heatpipes so they are also heating each other. 
There are 3 ways to lower the cpu temp:
- repaste the CPU with a better quality thermal paste. I recommend MX4. Many people like Kryonaut too which can also be good. Best performance could be achieved with liquid metal like Thermal Grizzly COnductonaut, however even if you are an experienced computer technician, I do not recommend using it! The reason why I do not recommend is that the surface of the 8750H's die is not perfectly flat like it was with the previous gen CPUs. You can put LM there, however after carrying around it might spill out because as I said the die is not perfectly flat. 

- enable Coolboost in Acer Quick Access

- undervolt with Throttlestop. It is easy and you can set it up in 5 minutes for it to automatically undervolt when the Windows starts. 

With these steps you can bring down the CPU temp under games to around 80C, maybe even lower.
