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:



As others have asked, desktop or laptop
But also where is it? If it’s a “desktop” but on the floor in a deep carpet, tucked against the dark corner of the room under a desk, that’s not going to help… bring it out into the air…
And for a laptop… lift it off the desk
I created an MDF raised deck for my laptop, with a massive slot where the fan intake is underneath, that really helped it breathe.
Looking to the future, if cooling is going to be a problem, I like to over spec’ the equipment and underutilise it - it’s better to run something twice as powerful at half the load… this knowledge came from the hifi world.
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.
