Replacement Fan for FCN FKNB Models

This DBTLAP cooling fan serves as a direct replacement part for compatible laptop heatsinks. It suits owners of FCN or FKNB series devices who need to restore cooling performance. Buyers who want a universal add-on pad with USB power and adjustable height should look elsewhere.

5V 0.5A Power and Part-Number Matching

The unit runs on a 5V .5A supply and carries the identifier 6-31-NK5S2-200 MMQR. Compatibility depends on an exact part-number match; the supplier advises checking photos and model numbers before ordering. No other voltage or connector variants are supported by this listing.

Tested Single-Fan Unit with DFB451005M20T Reference

Each fan is tested before shipping and ships as a single 1x Fan package. The DFB451005M20T reference and 200 marking help confirm fitment for the target heatsink. Systems that require dual-fan assemblies or higher airflow ratings fall outside this part’s scope.

Questions about this item

Which part number should I choose to match my laptop?

The listing identifies the replacement fan by part numbers FCN FKNB DFB451005M20T and 6-31-NK5S2-200 MMQR; compare these codes and the photos with your original fan before ordering.

What does the 5V 0.5A rating mean for daily use?

The fan draws 0.5 A at 5 V, so it runs from a standard USB port without needing an external power adapter.

How does the USB interface limit the fan?

Power is capped at the USB 5 V supply, so the fan speed and airflow are fixed by the 0.5 A current draw.
