Replacement heatsink fan for FCN FPSB laptops

This new DBTLAP cooling fan is built to match part number 6-31-NH5NN-100 and runs on a 5 V supply. It is intended for owners of compatible FCN FPSB models who need to replace a worn or noisy original cooler. Each unit is tested before shipping and the listing photos show the exact item you will receive.

5 V power and single-fan design set the practical

The cooler draws power from a 5 V header, so it can only operate within the voltage and current budget of that connector. A single fan assembly means airflow is limited to what one impeller can move through the heatsink fins. No additional speed controls or PWM headers are mentioned, so the fan runs at its fixed specification.

Direct drop-in for the listed part number

The package includes one fan that aligns with the 6-31-NH5NN-100 mounting points, giving a straightforward swap for that exact component. It comfortably handles the thermal load the original cooler was designed for in supported FCN FPSB chassis. Buyers needing a different voltage, a dual-fan module or a cooler for another laptop series will not be served by this part.
