Hey everyone, CPU temperatures have been a problem lately. I've tried a few fixes but the temps keep spiking up to around 100°C. When I first booted up, even with the system cold, they were between 95-100°C. No changes to BIOS or software recently. Recently moved into a new house and noticed this. Used MS Word for a short while before, so I didn’t really feel any throttling then. While driving, I took the GPU out, put it back in, and checked the thermal paste. It looked a bit corroded around the block—maybe not directly related. One hose feels warmer than the other, and there’s a sound of water moving inside, though it sounds loud. I’m testing a different cooler just to see if it helps, but I’m worried about pump speed fluctuations. Any advice would be greatly appreciated. Thanks!

Inspect for trapped air by moving the pump to its lowest position in the system (radiator facing upward). Gently shake the head and reapply fresh thermal paste. If the issue persists, the pump may be deteriorating, especially with corrosion around the copper coldplate, which could compromise the seal.

I believe it's time to swap out the AIO. It might be possible to repair it, but most AIOs are designed not to be fixed or refilled (though there are a few exceptions). With the presence of corrosion, I wouldn't risk it. Given your CPU's TDP of just 91W, you could use an air cooler that would work better and run quieter than the AIO for a much lower cost. Have a great day!
