Replacement CPU fan for ZenBook 431 and 4500 series

This new Vszerda cooling fan replaces the original unit in ASUS ZenBook UX431, UX431F, BX431, UX431FL, UX431FLC, UX431FA, UX431FAC, UX431FN, UX431DA, UM431DA, U4500F, S4500F, S431, S431F and UM431 models.

Sustained cooling for ultraportable workloads

Under continuous load the fan maintains airflow across the heatsink to keep processor temperatures stable during long compile jobs, video exports or extended browsing sessions. Its blade profile and motor are built for the thermal envelope of these slim chassis rather than short burst cooling.
