Replacement Fan for Select FCN and FLHF Laptops

This 5V 0.5A cooling fan and heatsink assembly carries part number 6-31-NH77N-101. It is built as a direct replacement for the original cooler in compatible FCN FMQ8 DFS5M325063B1N and FLHF DFS5K221153711 models. Each unit is tested before dispatch to confirm it spins correctly. Buyers who need a cooler for a different laptop series should look elsewhere.

Thermals Noise and Power in Normal Use

The fan draws 0.5A at 5V, matching the power budget of the original cooling module. It is designed to move enough air for the thermal profile of the listed laptops without exceeding the motherboard header limits. Acoustic output is consistent with a standard laptop cooler running at its rated voltage. Systems that require a higher airflow rating or a different voltage rail are not supported by this part.

Critical Compatibility Check Before Purchase

The single specification that decides fit is the exact part number 6-31-NH77N-101 paired with the model codes FCN FMQ8 DFS5M325063B1N or FLHF DFS5K221153711. Visual comparison with the product photos is essential because connector layout and mounting points vary across similar-looking units. Orders placed without confirming this match will not fit the target laptop.

Questions about this item

How do I install the 5V 0.5A fan and heatsink in my laptop, and what step do people often miss?

Match the 6-31-NH77N-101 part number to your FCN FMQ8 DFS5M325063B1N or FLHF DFS5K221153711 model, then connect the 5V 0.5A power lead before securing the heatsink — skipping the part-number check is the common error.

What maintenance or replacement will this cooling fan need over time?

The fan is a single moving part; expect to clean dust from the heatsink fins periodically and replace the entire 6-31-NH77N-101 unit if bearing noise or airflow drops.

What limit appears first when this cooler runs under sustained load?

The 5V 0.5A power ceiling caps maximum fan speed, so thermal headroom hits that electrical limit before the heatsink saturates.
