CPU overheating even at idle (80-90C) - SOLVED (AIO pump died)

Hello everyone,

The CPU from my DAW PC is overheating even at idle. When I turn it on in the morning everything seems fine but around 5-10 minutes even without loading any programs the fans start to get progressively louder to the point of almost sounding like a vacuum cleaner. When I try to restart the computer I get a bios message "error cpu high temperature". I access bios and the temperature reads 82ºC. I have checked windows task manager and the CPU meter is around 5-6% and there doesn't seem to be any processes in the background. I suspect it's something to do with the liquid cooler. All fans are spinning by the way. 2 case fans and 2 fans from the liquid cooler.

This is a PCSPECIALIST build from 2021 and here are the specs:

Yep, if all fans are running it's likely that the cooler has failed:
  • Pump has failed
  • Air trapped in pump head
  • Liquid has evaporated
  • Bad mounting
I'd say the pump failing is most likely.

Hi guys,

You are right the AIO pump has died.

Going do try to find a replacement or even better a new cooling system. Someone has recommended me the Noctua NH-U12 but it doesn't fit in all cases. We'll see what I can find.

Thanks a lot guys really appreciate your help.
