Yes, anti-cheat programs can sometimes affect hardware through system instability or resource overload.

It checks for suspicious software attempting to insert code or alter memory, and it also looks for unusual input patterns.
Since root access exists, it allows changes to voltage settings and can halt fans. That’s why Microsoft prioritized running software as the regular user instead of admin, though anti-cheat measures later compromised that protection.
However, fan control programs also rely on this 'gap' they need to function. The entire WinRing0 environment used by different tools is vulnerable in this way. I haven't observed anyone damaging a computer this way, so the anti-cheat system didn't compromise the supposed safety measures but simply reinforced them. Looking ahead, Microsoft intends to limit kernel-level permissions eventually, which could be significant.
It's essentially a malicious KM rootkit and we've seen those render computers useless before (Chernobyl, Mebroot, etc.) - once it's installed it runs on bare metal so it has the keys to the realm, it can do anything a remote malicious actor codes it to do, including corrupting the BIOS or wiping it completely, there's no physical switch to lock the chip to a read-only setting, so once you have access to the core code you can reprogram it the way you want, like if you had an external programmer. There's hundreds of reasons on why this is *really* wrong, it started with the CCP/Tencent malware "Vanguard" and spread like a wildfire, the best part? it's not stopping any cheaters at all , so it's not even good at what supposedly was created for, so, what's the actual reason behind it? yeah it might stop scriptkiddies using cheat engine or precoded programs, but not the actual cheaters who did their homework. Number 1 reason is it can be used as weaponized DRM enforcement. Imagine if you had the ability to permanently destroy an user's computer because he downloaded your game without paying, like, that's the level we're at, let that sink in for a minute, physically destroy someone's computer because he pirated your game, or your movie, or your book. And this malignant code is part of the program as a whole, can't be removed without recoding everything, and honestly no warez/scene groups are gonna do that.
