PSU fan stopped
Warning — Should be addressed soon
Symptoms
- PSU overheating
- PSU fan not spinning
- PSU shuts down from thermal protection
Step-by-Step Fix
Power off and check if the PSU fan is physically obstructed.
Clean dust from the PSU fan and vents.
If fan does not spin after cleaning, the fan motor has failed.
APW PSU fans can be replaced but require opening the PSU enclosure. This involves high-voltage components.
For safety, consider replacing the entire PSU rather than just the fan.
