Replacement Fan for FN9U Laptops

This DBTLAP cooling fan is a direct replacement part for laptops using the FN9U DC5V 0.5A specification. It operates at five volts and draws half an amp to maintain thermal performance. The unit ships as a single tested fan without additional mounting hardware.

Buyers Matching the Exact Part Number

This cooler suits owners who have verified the FN9U DC5V 0.5A DFS5K22B156734 EP DC28000T8F0 0203MH code on their original fan. It will not fit laptops that use a different voltage, connector layout or physical dimensions. Buyers needing a universal pad or a higher airflow design should look elsewhere.

Drop-In Cooling Component

The fan installs inside the existing chassis using the original screw points and power header. No external power brick or software control is required. Replacing a worn unit restores the intended airflow path and frees the system from thermal throttling during sustained loads.
