Replacement cooler for listed notebooks

The OEM Industries KFB0505HA is a 5 V 0.38 A CPU air cooler built for specific notebook models including F8, A8, A8F, Z99, X80, N80, N81, F3J, F8S, Z53J, Z53 and M51. It uses a three-wire three-pin connector and a ball-bearing fan without LED lighting. The unit is supplied new and intended as a direct drop-in replacement for the original cooler in those machines.

Simple swap with connector care

Installation consists of removing the old cooler, cleaning the mating surfaces, applying fresh thermal compound and plugging the three-pin header into the motherboard fan socket. The most common issue is misaligning the three-pin connector or leaving the mounting screws uneven, which can cause vibration or poor thermal contact. The ball bearing spins freely but offers no speed feedback beyond the third wire, so verify the fan spins up immediately after power-on.

Verify model and voltage before ordering

Check that your notebook appears in the supported list and that the original cooler carries the KFB0505HA marking and a 5 V 0.38 A rating. Confirm the motherboard uses a three-pin fan header with the same pinout and that the mounting hole pattern matches the replacement. If your machine uses a different voltage, connector or bracket layout this cooler will not fit or function correctly.

Questions about this item

How can I confirm the KFB0505HA cooler is running correctly after installation?

Check that the fan spins smoothly and the CPU temperature drops under load in the BIOS or monitoring software.

What comes with the KFB0505HA cooler and what must I source separately?

The package includes the cooler with a 3-pin connector; thermal paste and mounting hardware for your specific laptop model are not included.

Match the cooler to your exact model — F8, A8, A8F, Z99, X80, N80, N81, F3J, F8S, Z53J, Z53 or M51 — as no universal variant is offered.
