Replacement Heatsink Fan for SUNON

This new cooling heatsink fan is a direct replacement for the SUNON EG50040S1-1C040-S9A model. It operates at 5V with a power rating of 2.25W. The package includes one fan unit tested before shipping. It is intended for laptop owners repairing a specific cooling assembly.

Sustained Cooling Operation

The fan draws 2.25W continuously while spinning to move air across the heatsink. This steady power draw supports consistent airflow during extended workloads rather than short bursts. Each unit is tested before shipping to verify it runs reliably under continuous operation. Buyers who need variable speed control or PWM signalling should verify the connector matches their board.

Exact Part Number Compatibility

The single specification that decides fit is the exact part number SUNON EG50040S1-1C040-S9A with the AT2GA001SS0 reference. You must match this number to your original fan to ensure 100% compatibility. Check the photos against your old unit before purchasing. If you are unsure, provide your model number for verification before ordering.
