Replacement CPU fan for HP TPN Q245 and Q246

This DBTLAP cooling fan matches part number EG50040S1-1C290-S9A and HP spare M14818-001. It is a direct replacement for the original cooler in those laptop models. The unit ships new and includes one fan that has been tested before dispatch.

Thermals, noise and power draw in normal use

The fan runs on a 5 V supply and draws 2.50 W through its four-pin connector. This low power rating keeps battery impact minimal during everyday tasks. The four-pin interface allows the system to regulate speed for quiet operation.

Behaviour under sustained load

When the processor stays under heavy load the fan can maintain higher speeds continuously because it is powered directly from the motherboard header. The 2.50 W rating supports steady airflow without exceeding the laptop's thermal budget. Compatibility should be confirmed against the photos and part number before installation.

Questions about this item

How do I install the EG50040S1-1C290-S9A fan and which step is often missed?

Disconnect the battery, remove the old fan, plug the 4PIN connector firmly into the motherboard header, then secure the screws; the step often missed is reconnecting the battery before testing.

What maintenance or replacement will the EG50040S1-1C290-S9A need later?

Clean dust from the blades and heatsink every few months with compressed air; replace the fan if bearing noise appears or airflow drops below specification.

What limit appears first on the EG50040S1-1C290-S9A during sustained use?

The 2.50W power envelope limits maximum RPM; prolonged loads hit this thermal ceiling before the 4PIN control loop can increase speed further.
