CPU Cooling Fan Replacement for ASUS S400 S400C S400CA S400CB S400E X402C X402E X502C F402C Ultrabook Cooler

This brand new laptop CPU cooling fan is a dedicated replacement accessory for ASUS lightweight touch ultrabooks, compatible with S400, S400C, S400CA, S400CB, S400E, X402C, X402E, X502C and F402C series notebooks. It comes with a standard 4-wire PWM plug that seamlessly cooperates with the laptops built-in thermal management system to dynamically adjust fan rotation speed under different CPU loads.

Designed with slim optimized curved turbine blades and durable long-life silent brushless motor, it provides stable concentrated airflow to rapidly carry away CPU accumulated heat. It effectively fixes common fan faults such as loud rattling buzz, persistent high-temperature alerts, slow system running speed and unexpected automatic shutdown caused by aging original cooling fans. The integrated anti-vibration cushion greatly reduces vibration noise during online classes, 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 fully consistent with the original factory fan, no wire cutting or chassis modification required for easy self-repair or professional maintenance. It is a cost-effective cooling spare part to restore stable heat dissipation performance of ASUS S/X/F series thin touchscreen laptops.
