I recently had a power outage that caused my PC to shut down. After restarting, everything seemed fine until a few minutes in, when I got a blue screen with a kernel panic error saying "Fatal exception in interrupt." On trying to boot again, I was met with a "CPU Fan speed detection error!" message and I couldn't even get to my OS. After entering the BIOS, I noticed it couldn't read the fans, voltages, or temperatures. I reset the CMOS and while the BIOS now shows some info, it still marks the AIO pump and CPU fan as "N/A" and my CPU temp is way too high, around 85°C at idle. Is my AIO pump dead, or could this be a motherboard issue?

A quick test is to touch the tube of the AIO when your PC is running. If you feel water flowing through it, then it might be your motherboard causing the issue. If not, the pump could be dead. Also, a tip for the future: unplugging your PC from the outlet before power returns can help avoid damage from surges.
Thanks for the tip! I tried to check the tubes but I'm not sure what I'm looking for. How am I supposed to tell if the liquid is flowing? Also, if it's a motherboard issue, what might be causing the high CPU temperature at idle?
It sounds like your motherboard took a hit during the power outage. Sometimes, sudden power cuts can cause spikes that damage parts, including your AIO cooler. I'd recommend checking the pump first to confirm if it’s working or not.
Definitely recommend that! Consider getting a UPS for better protection against spikes and outages.
