I was woken up by my PC, which had all fans at 100% creating a monstrous cacophony

When I tried to turn on my monitor, it stayed blank, indicating that there might have been no signal. I could only force a restart by flipping the PSU switch. When I restarted, I found no obvious culprit for my fans being at 100%.

Not sure what to look for in event viewer, but most errors seemed to come from the fact I irregularly shutdown the computer with the PSU switch.

Around 30 minutes before I was awoken, event viewer claimed that Security Protection Service was restarted.

Fans were controlled via Fan Control and when restarted, the settings were still appropriate - followed my fan curve.

What can I do to troubleshoot the cause for this?
