How does one optimize for better system temperatures on Linux while doing heavy tasks (e.g. gaming) during summer heat.

Are there tools for creating 'gaming/balanced/economy' profiles for example that limit the GPU and CPU depending on the requirements?

Should I find a way to customize fan speeds?

I am trying to find everything I should do from the software perspective before I move on to buying better cooling hardware.

I am currently reaching 100+ celsius temps maximum on both the GPU and CPU while gaming, on idle it's like this:

What kind of cooling do you have? Do your fans actually run? Like do they ramp up when your CPU is hitting 100+?

Probably worth changing your thermal paste, slightly excessive paste is better than too little paste. Whilst there, make sure you’ve removed the film from the CPU cooler and make sure it’s seated properly.

Go into your bios and adjust your fan curve for CPU, whilst you’re there turn off zero RPM or adjust its temperature so that the fans turn on sooner. Use something like LACT do the same for your GPU.

Your idle temps aren’t too bad but something isn’t right if you’re hitting 100C+ at load. Especially on that CPU.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
