This brand new laptop CPU cooling fan is a dedicated replacement spare part for Lenovo mainstream daily notebooks, compatible with G40-30, G40-45, G40-70, G40-75, G40-80, Z40-70, Z40-75, Z50-70 and SR1000 series, covering sub-models G40-70AT, G40-70M, G40-70MA, G40-70AM, Z40-70A, Z40-70AP, Z50-70A, Z50-70AP.
It comes with standard 4-line PWM wiring that works seamlessly with Lenovo built-in thermal control system to dynamically adjust fan rotation speed under different CPU loads. Optimized curved fan blades deliver stable concentrated airflow to rapidly exhaust CPU heat buildup inside the chassis.
It effectively solves common fan faults including loud rattling buzzing noise, persistent high-temperature alerts, system slowdown and unexpected auto power-off caused by aging or dust-clogged original cooling fans. Integrated anti-vibration foam structure greatly cuts vibration noise during online courses, document editing and multimedia browsing.
Every cooling fan undergoes strict airflow, voltage and durability quality inspection before shipment. The fan housing size, screw hole layout and cable length are 100% consistent with original factory fan, no wire cutting or chassis modification required for easy self-repair or professional maintenance. It is an economical cooling spare part to restore stable heat dissipation performance of Lenovo G/Z series 14-inch daily laptops.
