Replacement fan for MF75100V1-C040-S9A

This DC5V 2.25W 4-pin cooling fan is built as a direct replacement for the MF75100V1-C040-S9A assembly. It suits laptop owners and repair technicians who need to restore original airflow without modifying the heatsink or wiring harness.

Upgrade from a worn or noisy original

Swapping the factory unit is worthwhile when the old fan rattles, spins slowly or has stopped entirely. The four-pin connector matches the motherboard header, so the swap restores PWM control and thermal curves exactly as designed.

Cooling capacity for the designated heatsink

The fan delivers the airflow specified for this part number, keeping the CPU within its normal operating envelope under typical loads. It will not fit other laptop models or coolers that use a different mounting pattern, voltage or connector pin-out.
