Please Help What is wrong with my PC?

System specs


Intel Core i7 7700k

Corsair H100i v2 water cooler

Geforce RTX 2080

Seasonic X650 PSU


I turned on my PC today and all off a sudden the water cooler radiator fans spun up to maximum and CPU temp reached 100 degrees. Just an hour ago it was working fine. I turned it off and when I turned it back on an hour later this happened. In Corsair Link software the pump is showing 0 RPM but I have never used this software before so I don’t know what it used to show before. All wires are secure as I didn’t even touch the internals. Is my motherboard dead or what fault is it? Thanks in advance for helping.

If the pump is showing as 0 RPM then that's likely your issue. No coolant flow = it's not gonna do anything so the heat will just sit in the block and you get overheating, throttling, then shutdown. Main problem with AIOs is they have a lot more failure points than air coolers and break more often than custom liquid cooling stuff, which is much beefier.
