Compatible Toshiba Satellite models

This replacement CPU cooling fan fits Toshiba Satellite L40, L40-A, L40D, L40D-A, L40t-A, S40, S40DT, S40DT-AT01M, AT11M, S40D-A, S40T-A and L45 series laptops. It matches part number DFS531305M30T and FCFB for direct installation. Buyers with different model numbers should verify compatibility before ordering.

Continuous thermal management

The fan runs at 5 V and 0.5 A to provide steady airflow during extended workloads. Each unit is tested before shipping to confirm reliable operation under sustained load. The design targets consistent heat dissipation rather than short bursts of speed.

Replaces worn or noisy original fan

This part replaces a failing factory cooler that has become loud or ineffective. The upgrade is worth it when temperatures rise unexpectedly or the original fan stops spinning. It is not for users needing additional external cooling pads or multi-fan setups.
