Replacement Fan for Lenovo B300 B30R3

This cooler fan is a direct replacement part for Lenovo B300 and B30R3 laptops. It is intended for owners whose original cooling fan has failed or become noisy. The component restores the factory airflow path without modification.

Single Fan Cooling Constraint

The unit uses a single fan assembly to move air through the heatsink. Thermal headroom is limited by that single airflow path, so sustained heavy loads may still throttle the processor. Dust buildup on the fins will reduce effectiveness faster than dual-fan designs.

Upgrades a Worn or Failed Original Fan

This part replaces the original Forcecon, ADDA, Sunon or Kipo fan shipped with the laptop. The jump is worth it when the old unit rattles, spins slowly or stops entirely. It is not for buyers who want additional cooling capacity beyond the stock specification.
