I recently had a strange experience when my PC suddenly woke me up with all the fans running at full blast. I tried to turn on my monitor, but it stayed blank, suggesting there was no signal. The only way to restart my PC was by flipping the PSU switch. After rebooting, I couldn't find any clear reason for the fans running at 100%. I checked the event viewer but mostly found errors related to shutting down the computer irregularly using the PSU switch. Interestingly, about 30 minutes before the wake-up incident, the event viewer noted that the Security Protection Service had restarted. I use Fan Control for my fans, and when I restarted, the settings were still correct according to my fan curve. I'm looking for any advice on troubleshooting this issue.

For me, too, running fans at full speed happened when I shut down apps or during Windows shutdown. It might be related to your system settings or how the components interact under certain conditions. Are you using the latest drivers? It’s one of those tricky computer riddles!
I had a similar experience after playing games like Monster Hunter. My PC would freeze up completely, screen black out, and fans would go wild. The only way out was a forced restart. It could be some heat issue or a hardware hiccup, but I couldn't pinpoint the exact cause.
There are a few potential reasons this could happen. It could be a virus running in the background, such as one that mines cryptocurrency when your PC is idle. Alternatively, it may just be a Windows update that triggered the fans. I'd recommend checking the Event Viewer for any weird logs around the time it happened. Look for driver failures or crashes. Also, provide some basic checks—disabling Wake-on-LAN in your BIOS and ensuring no unnecessary wake timers are set in Windows can help.
Yeah, it's annoying. Sometimes it feels like the system just gets confused!
This has happened to me when my GPU crashes or when Windows has a hiccup with sleep mode. It sounds like that could be the case here too. Just try to monitor your GPU and see if there’s a pattern when it happens. Otherwise, sometimes these issues resolve themselves after a while without clear reasons why.
Or it could be just one of those fun Windows glitches! I've experienced it too.
