Possible Causes

Dust buildup in fan, Worn fan bearings, Fan connector loose, Failed fan driver on PCB

How to Fix / Troubleshooting

Safety first: Fans are near live parts; isolate power before servicing.

  • Listen for fan: During high-current charging, you should hear the internal fan on models that have one. Absence or grinding noises indicate an issue.
  • Open and clean: With power off, open the unit and gently clean dust from the fan blades and surrounding area using compressed air or a soft brush.
  • Check connector: Ensure the fan’s power connector is firmly seated on the main PCB or power module.
  • Replace fan: If the fan does not spin freely by hand or is noisy, replace it with the specified cooling fan module.
  • Driver fault: If a new fan does not run, the fan driver circuit on the main PCB or power module may be faulty.
