Replacement CPU Cooling Fan for HP ProBook 4545S

This new DBTLAP cooling fan is a direct replacement part for HP ProBook 4545S and 4745S laptops. It matches part numbers DFS551205ML0T, FC5H and 23.10616.012. The unit operates at 5V and draws 0.5A. It is intended for owners of those specific models who need to replace a worn or failed internal cooler.

Upgrading from a noisy or failing original cooler

The jump is worth it when the original fan runs loud, spins inconsistently or has stopped entirely, causing thermal throttling or shutdowns. Installing this unit restores the factory cooling profile without modifying the laptop. It is not for users seeking higher airflow than the original design or for any laptop outside the listed ProBook series.

Fits inside the existing chassis using the stock

The fan connects to the motherboard header used by the original cooler and requires no extra cabling or adapters. It frees up no additional space because it occupies the same internal volume as the part it replaces. Builders working on other HP models or custom projects cannot use this cooler without verifying identical mounting and connector geometry.

Questions about this item

Will the 23.10616.012 fan align with the mounting holes on an HP Probook 4545S?

The 23.10616.012 is listed for HP Probook 4545S and 4745S; compare the screw-hole pattern in the photos to your original fan before fitting.

What is the common mistake when replacing the DFS551205ML0T fan in these models?

Forgetting to disconnect the battery and the 5 V 0.5 A fan cable before removing the heatsink screws, which can short the motherboard.

When should the FC5H cooling fan be cleaned or replaced?

Clean the heatsink fins and fan blades when temperatures rise above normal; replace the unit if bearing noise appears or airflow drops noticeably.
