Laptop Cooling Fan for Dell Inspiron 15

This replacement cooling fan is designed for specific Dell Inspiron 15, 15R, 17 and 17R laptops. It matches part numbers including 74X7K, i15RV-1667BLK and DC28000C8F0. The component suits owners of listed models who need to restore original thermal performance. It is a direct fit for the supported chassis.

Installation Requirements and System Impact

The fan mounts inside the existing laptop cooling assembly using the original screw points and connector. No additional hardware or adapter cables are required for the listed models. Replacing a worn unit frees the processor from thermal throttling and reduces internal temperatures. Buyers whose laptop model is not in the compatibility list should verify fitment before ordering.

Questions about this item

Will the 74X7K fan keep up with sustained loads on a Dell Inspiron 15 5521?

The 74X7K is a direct replacement cooler for the Inspiron 15 5521 and matches the original thermal design for continuous operation.

How much noise and heat does the i15RV-1667BLK produce when running all day in a 15.6" chassis?

The i15RV-1667BLK uses the same DC28000C8F0 specification as the factory fan, so acoustic and thermal output remain at stock levels.
