Replacement CPU fan for Lenovo B-series laptops

This new, original CPU cooling fan is designed for Lenovo B50-70, B40-30, B40-45, B40-70, B50-30 and B50-30A models. It replaces part number EG60070S1-C070-S99 directly. The part restores factory cooling performance for compatible machines. Buyers with other laptop series or custom cooling setups cannot use this component.

Thermals, noise and power in normal use

The fan draws power from the laptop motherboard header and spins to match thermal demand. Acoustic output varies with processor load and BIOS fan curves. No separate power rating or noise specification is provided by the supplier. Installers should verify the connector matches the original before fitting.

Questions about this item

How do I install the EG60070S1-C070-S99 CPU fan in a Lenovo B50-70, and what step is often missed?

Remove the bottom case, disconnect the old fan cable from the motherboard, unscrew the heatsink assembly, swap the fan, then reapply thermal paste on the CPU before refitting the heatsink.

What maintenance will the EG60070S1-C070-S99 fan need over time?

Blow dust from the heatsink fins and fan blades with compressed air every few months; if the bearing becomes noisy or airflow drops, fit a new EG60070S1-C070-S99 unit.
