[Solved] Limit max turbo boost frequency for intel i7-8750H

Hi!

I have a laptop with an intel i7-8750H processor. Due to a poor thermal design, when the CPU and GPU are working--usually gaming--it gets too hot and the cpu starts throttling.

What helps me on Windows is using Throttlestop to limit the maximum turbo boost frequency. My processor's base freq is 2.20GHz, with a max turbo speed of 4.1GHz. By setting a smaller upper bound, like 3.6GHz, I can play most games without any thermal issues.

Now the problem is I am not aware of any tool that can do a similar thing in arch linux. I'm aware of intel-udervolt, and I'm already using it, but that's not what I'm asking about.

I've been reading the kernel documentation on cpu frequency governors (https://www.kernel.org/doc/Documentatio … ernors.txt), which seems to be what I need, but I don't find anything relevant to set the scaling_max_freq, it's just mentioned as some kind of constant value (please correct me if I'm wrong!).

Ok, it seems I just needed to RTFM a bit more...

From the wiki: https://wiki.archlinux.org/index.php/CP … requencies

I'm marking this as solved, but I'm still interested if anyone has more advice related to this.
