Vszerda CPU Cooling Fan 4-Wire for HP 17 Series

Replacement CPU fan for HP 17 Series

This Vszerda cooling fan replaces the original CPU cooler in HP Notebook 17-X, 17-Y, 17-AK and 17-BS series laptops. It matches part numbers 856681-001, 856682-001 and 926724-001. The unit ships new with a tube of thermal paste included. Installers should verify the old fan against the photos and part number before fitting.

Four-wire PWM connector limits control options

The fan uses a 4-wire lead ending in a 4-pin plug that carries power, ground, tachometer and PWM signals. Speed regulation depends entirely on the laptop's embedded controller firmware; the fan itself has no independent temperature curve. If the mainboard header is damaged or wired for 3-pin voltage control only, the fan will run at full speed constantly.

Compact assembly with no heatsink supplied

The package contains only the motor-and-blade module; the existing heatsink must be reused or sourced separately. Mounting points align with the original HP chassis screw pattern for the listed 17-inch models. The free thermal paste tube covers one CPU application, so builders should clean both surfaces thoroughly before reassembly.
