Compatible Cooling Fan for Satellite L645D

This replacement CPU cooler is built for Toshiba Satellite L645D-S4040 and L645D-S4056 notebooks. It serves owners who need to restore factory cooling performance after a bearing failure or airflow loss. The unit ships as a single tested fan assembly ready for installation.

Verify Exact Model Before Purchase

Confirm that your laptop carries the precise model numbers L645D-S4040 or L645D-S4056 printed on the service tag. Connector layout, mounting hole spacing and shroud shape differ across similar Satellite chassis, so visual comparison with the original part is essential. Buyers who need a different Satellite variant or a universal pad will not be served by this specific cooler.

Steady Thermal Performance Under Load

Each fan is bench-tested before dispatch to ensure it spins up and maintains rated airflow without stalling. During extended workloads the motor sustains consistent RPM to dissipate heat from the processor and chipset. The assembly contains no additional heat pipes or secondary blowers, so cooling capacity matches the original single-fan design.
