Replacement CPU Fan for VivoBook Models

This new CPU cooling fan carries part number NS85C05-18L30 FL6K and fits Asus VivoBook series including X512, F512 and A512 chassis. It is intended for owners of those specific laptops who need to replace a worn or noisy original cooler. The package contains one fan unit ready for installation.

Single Fan Unit in Package

The bundle supplies exactly one CPU fan with no additional brackets, thermal paste or mounting screws included. Buyers must reuse existing fixings from the old cooler or source compatible hardware separately to complete the repair.

Verify Part Number Before Ordering

Questions about this item

How often will the NS85C05-18L30 FL6K fan need cleaning or replacement?

Dust buildup on the blades is the main wear factor; cleaning every 6 to 12 months keeps airflow steady, and the sleeve bearing typically lasts several years before a full swap is needed.

What stops the fan from cooling the VivoBook X512 during a long compile or render?

The single 5 V header limits maximum RPM, so sustained loads hit the fan's airflow ceiling before the heatsink saturates.

How loud and hot does the FL6K get when the laptop runs all day?

At full duty it produces a noticeable but low-pitched whir, and the motor housing stays warm to the touch without exceeding the 5 V supply's thermal envelope.
