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:

that's not how stress testing works. Different games will present different load to a given combination of hardware. Besides that, computers are used for many more tasks in addition to gaming. Careless re-tuning can lead to a lapse in system integrity in ways that aren't immediately apparent, but damaging all the same.

    you may never have done this kind of optimization before, but when it comes to undervolting, it becomes clear pretty quickly that the wrong settings were chosen. so let me repeat: separate load testing makes no sense for someone who just wants to play games in a cool room during the summer, it’s just a waste of time and electricity. and let's forget about the careless re-tuning thing; we obviously all undervolt with care, precision, and a ceremonial blessing.

    I work in client gfx at an IHV; I am intimately familiar with system integrity routines, component stress testing and tuning, particularly with DIY systems. Nothing about what I've recommended is "a waste of time and electricity" when you're privy to the breath of defects averted in the field after following proper guidance.

    Don't take your own experiences for granted, if this person was familiar with the concept, they wouldn't need to ask.

    have you ever tried undervolting yourself?

    Extensively, across various compute and graphics generations. I presently do so even now, though I wouldn't offer that to a user completely unfamiliar with the domain as some kind of silver bullet; it doesn't sidestep package power limits.

    have you ever had any issues that weren't noticeable within the first 10-15 minutes of running under load?

    yes, absolutely, though I've seen it much more amongst other end users.

    As I've mentioned, games will load your system differently from one another. Someone who claims their system is stable with their custom tunings in every game except for something new that they've recently installed does not have a stable system. this is a case my colleagues and I see over and over.
