Have you noticed the same thing happening on your Windows 11/10 desktop PC? If so, this is how you can fix GPU fans that repeatedly start and stop spinning.

Why does my GPU fan stop spinning?

Users have said loose RAM sticks can cause the fans to repeatedly start and then stop spinning. Those users resolved the issue by removing and reinserting their RAM modules. A faulty or loose CMOS battery can also cause this GPU fan issue. Some users have resolved the error by removing the CMOS batteries from their PCs and reinserting them.

Are GPU fans always supposed to spin?

The fans only start spinning when GPUs reach certain temperatures. The temperature threshold for fans to start spinning can vary, but 50-55 degrees Celsius is a common mark. Nor is it always entirely unusual for GPU fans to start and then stop spinning. GPU fans usually spin and then stop on startup soon after turning on a PC.

How do I fix GPU fans that spin and then stop?
