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:

System info:



It’s a desktop on the floor under my desk, so there could definitely be some intake airflow problem there. It would be extremely impractical to bring it out, but maybe a human fan would help with that.
Make sure it has at least a few inches of clearance at the back. Also many cases/PSUs have fans on the bottom, if yours does then raising it up on some feet can really help.
