Replacement CPU fan for Latitude 5400

This new DBTLAP cooler fan is built for the Dell Latitude 5400 using part numbers FL39, DFS5K12304363Q, DC28000MRFL and 0MXH2W. It arrives as a single tested unit ready to replace a worn or noisy original. Installers should verify the photos match the existing fan before fitting.

Upgrading from a failing stock cooler

The part replaces the factory fan when bearings wear out or airflow drops below spec. The jump is worth it when the laptop throttles under load, the fan rattles or the system logs thermal warnings. It restores the original cooling curve without modifying the heatsink or motherboard.

Cooling capacity for daily workloads

The fan handles typical office tasks, web browsing and video playback while keeping the CPU within its normal temperature range. It runs out of headroom during sustained heavy renders, long compile jobs or gaming sessions that push the processor continuously. Users needing higher airflow for those loads should look at external cooling pads instead.
