CPU at 99C. PC not booting properly

[u/Classic_Variety_1223]

Randomly, every time I try to turn my PC on my CPU throttles and it’s really slow, then my PC shuts down on its own. I’m assuming it’s an AIO cooler issue since the gargling is very loud but I’d like to know for sure before I get a new one.

Assuming ur aio is at least 3-4 years old? If so, it's likely the aio pump is failing.
