Replacement fan for FCN FLLB laptops

This 4-pin cooling fan is a direct replacement part for FCN FLLB laptop models. It operates at 5 V and draws 0.5 A from the system header. The connector and mounting match the original DFS5K12304363N specification. Buyers who need a different voltage or pin layout cannot use this unit.

5 V 0.5 A power envelope

The motor runs on a 5 V rail with a 0.5 A current limit, giving a modest thermal budget for thin-and-light chassis. It handles everyday office loads and light media playback without saturation. Sustained gaming or rendering workloads will exceed the available airflow headroom. Buyers who want higher static pressure for heavy loads cannot get it from this part.

Low-speed thermal profile

At the rated voltage the fan spins quietly enough for library or meeting-room use. Power draw stays at 0.5 A, so battery impact is minimal during normal operation. Acoustic output rises only when the controller requests maximum duty cycle. Buyers who need silent operation under full load cannot achieve it with this cooler.

Questions about this item

Will this 4-pin DC5V 0.5A fan connect to the existing motherboard header on my FCN FLLB laptop?

The fan uses a 4-pin connector rated for DC5V 0.5A, matching the specification printed on the original FCN FLLB unit.

How can I confirm the DFS5K12304363N fan is spinning correctly after installation?

Listen for steady airflow from the vents and verify the laptop no longer throttles under load; each unit is tested before shipping.

Does the package include mounting screws or a cable adapter, or just the fan itself?

The box contains only the 1x cooling fan; screws, brackets or adapters are not included and must be sourced separately.
