Replacement CPU cooler for Lenovo B40 B50 E40 E50

This new internal fan fits Lenovo B40, B50, E40-70, E50, B40-70, B50-30 and B50 models. It replaces a worn or noisy original cooler to restore proper airflow over the processor. The part is designed for direct installation in the listed chassis without modification. Buyers needing a cooler for other Lenovo series or desktop sockets cannot use this item.

Thermals noise and power draw in normal use

The fan spins to move heat away from the CPU during typical workloads. Acoustic output remains consistent with the original factory cooler profile. Power is drawn from the standard motherboard header at the rated voltage for these models. No additional power adapters or external controllers are required for operation.

Questions about this item

How do I install the CPU fan on my Lenovo B50-30 and which step is often missed?

Remove the bottom case, disconnect the old fan cable from the motherboard header, unscrew the heatsink assembly, replace the fan, reapply thermal paste on the CPU, then reconnect the cable before closing the case.

What maintenance will this CPU cooler fan need later?

Clean dust from the heatsink fins and fan blades every six to twelve months using compressed air; replace the fan if bearing noise appears or airflow drops noticeably.
