Replacement CPU Fan for HP ProBook 4440S, 4441S.

This new cooling fan is built to fit HP ProBook 4440S, 4441S, 4445S and 4446S laptops. It matches part numbers 23.10605.001 and 683651-001. Each unit is tested before dispatch to confirm 100 percent operation. It suits owners of these specific models who need a direct drop-in replacement for a worn or noisy original cooler.

Sustained cooling performance

The fan is designed to maintain airflow during extended workloads rather than only short bursts. Because every unit is individually verified, it should spin up reliably when the system temperature rises. The manufacturer notes that the fans are sourced from Forcecon, ADDA, Sunon, Kipo or equivalent suppliers depending on stock, so exact acoustic and thermal curves may vary between units.

Straightforward installation with caveats

Installation follows the standard laptop teardown process for the listed ProBook chassis. The package includes 1 x fan only; no screws, thermal pads or cables are supplied. Buyers must compare the connector and mounting holes against the original part before fitting. If the pinout or bracket layout differs, the fan will not seat correctly, so verify compatibility carefully before proceeding.

Questions about this item

Which connector must the motherboard already have for this 683651-001 cooler to plug in?

It uses the same 4-pin PWM connector found on HP ProBook 4440S, 4441S, 4445S and 4446S mainboards.

Will the Forcecon or Sunon unit I receive fit the heatsink screws on my 4445S?

Yes — every variant shares the identical mounting hole pattern and screw positions as the original 23.10605.001 part.
