DELL Inspiron 14R replacement CPU fan

This new DBTLAP cooling fan fits DELL Inspiron 14R models 5435, 3543, 3437, 3442 and 3542. It also matches part numbers V2421, M431R, 23.10784.021, DFS481305MC0T and FC39. The unit runs at 5V and draws 0.5A. One fan is included in the package.

Upgrade when the original cooler fails

Replace the factory fan when it becomes noisy, spins irregularly or stops cooling the processor. The jump is worth it if your laptop throttles under load or shuts down from overheating. Buyers who need a dual-fan assembly or a complete heatsink module will not find that here.

Verify the exact part number before ordering

Compare the photos with your existing cooler to confirm the connector, screw holes and cable routing match. If you are unsure, provide your laptop model number for a compatibility check. Ordering the wrong part number will prevent a proper fit.
