Replacement CPU fan for ZenBook UX431 series

This Vszerda cooling fan replaces the original CPU fan in compatible A.SUS ZenBook UX431 series laptops. It matches part number DFS5K121154915 FLCB and fits models including UX431F, UX431FL, UX431FA, UX431FN, UX431DA, UM431DA, U4500F, S4500F, S431, S431F and UM431 series.

Upgrading from a worn or noisy original fan

Install this fan when the factory cooler becomes loud, spins irregularly or stops cooling the processor effectively. A direct swap restores proper airflow without modifying the heatsink or motherboard. The jump is worth it if thermal throttling appears under load or the laptop shuts down from overheating.

Verify the exact part number before ordering

Confirm that your laptop uses part number DFS5K121154915 FLCB by checking the sticker on the existing fan or the service manual. Connector layout and mounting holes must match the confirmation picture supplied with this listing. Buyers who need a fan for a different ZenBook series or a non-listed model cannot use this part.

Questions about this item

Will the DFS5K121154915 FLCB fan fit my ZenBook UX431FL chassis?

Yes, the fan is listed as compatible with the UX431FL and the wider UX431 series, matching the original part number DFS5K121154915 FLCB.

What is the tricky step when replacing the fan on a UX431FA?

Disconnect the battery before removing the motherboard screws; the fan cable sits under the board and is easily torn if the board is lifted too early.

How often should I clean the heatsink fins on this UX431FN replacement fan?

Blow compressed air through the fins every six to twelve months; dust buildup reduces airflow and forces the fan to spin louder.
