Compatible Laptop Fan for Lenovo B480 B485 B490

This replacement cooling fan fits several Lenovo laptop models including the B480, B485, B490, M495, B590 and E49 series. It uses a four-pin connector for motherboard control. The part is designed for internal installation by technicians or experienced users. Condition is new.

Four-pin connector limits speed control

The four-pin interface provides PWM speed regulation only on motherboards that implement the matching header and firmware. Older or entry-level boards may lack the necessary circuitry, leaving the fan running at fixed voltage. Buyers whose systems use a three-pin header or proprietary fan control will not gain automatic speed adjustment. No other interface or protocol is supported by this component.
