Optimize system for cooler temperatures (lemmy.ml)

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:

I got a tower stand, the bottom of the tower had completely filled with dust and there was no airflow from there, the wheels are also very convenient for cleaning under there.

I also cleaned the dust inside and re-applied new thermal paste, neither of which I had done for quite a while, and it already improved my temps by a lot, about 20 celsius cooler max for both the cpu and gpu.

Here are the temps after a gaming session:

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.
