Replacement CPU fan for HP ProBook 430 G8

This new DBTLAP cooling fan is built as a direct replacement for the EG70040S1-C140-S9A unit inside the HP ProBook 430 G8. It suits owners and repair technicians who need to restore factory cooling performance after a bearing failure or noise issue. The package contains one tested fan ready for installation.

Four-pin DC5V 2.50W connector match

The single specification that decides fit is the four-pin DC5V 2.50W power interface paired with the EG70040S1-C140-S9A part number. Buyers must verify their existing fan carries the same part number or the HP spare reference M33085-001 TPN Q27C; a different pin count or voltage will not work.

Thermals and acoustics in normal use

The fan draws 2.50 watts at five volts, spinning only as fast as the laptop's thermal controller demands. Under typical office workloads it runs quietly, ramping up during sustained loads to keep CPU temperatures in check. Each unit is tested before shipping to confirm smooth operation and correct speed reporting.

Questions about this item

What does the 2.50 W rating mean for cooling inside my ProBook 430 G8?

It draws 2.50 W at 5 V, giving the fan enough power to spin at its rated speed and move air across the heatsink in the 430 G8 chassis.

How does the 4-pin connector affect fan control on the HP ProBook 430 G8?

The 4-pin PWM header lets the laptop vary speed precisely, so the fan runs quieter at low load and ramps up only when the CPU needs it.

Will the EG70040S1-C140-S9A fit the mounting points on a TPN Q27C motherboard?

Yes, it matches the original M33085-001 screw pattern and shroud shape for the TPN Q27C board used in the ProBook 430 G8.
