Replacement Fan for HP Pavilion 15-CW/15-CS

This four-wire cooling fan replaces the original L25584-001 unit in HP Pavilion 15-CW and 15-CS laptops with integrated graphics. It fits motherboards marked TPN-Q208 and TPN-Q210. The package contains one black fan ready for installation.

Four-Pin PWM Control for Quiet Operation

The 4-wire connector enables pulse-width modulation so the system can vary fan speed precisely. Under light loads the fan runs slower, reducing noise and power draw. When the CPU temperature rises the firmware increases speed automatically to maintain safe thermals.

Direct Swap for Failed or Noisy OEM Fans

This part replaces a worn, noisy or failed original cooler without modification. The upgrade is worth it when the existing fan rattles, spins unevenly or triggers thermal throttling during normal work. It is not for buyers needing a second fan for a dual-fan chassis or a higher-airflow design than the stock specification.

Questions about this item

How is the L25584-001 cooling fan installed in an HP Pavilion 15-CW or 15-CS, and which step is often missed?

Remove the bottom case, disconnect the old 4-wire connector, then secure the new fan; the step people skip is reapplying thermal paste on the CPU and GPU contact points.

What maintenance or replacement will the L25584-001 fan need over time?

Dust buildup on the heatsink fins reduces airflow, so clean it with compressed air every few months; replace the fan if bearing noise appears or RPM drops.

What limit appears first when the L25584-001 runs under sustained load?

The 4-wire PWM interface caps maximum speed, so the fan hits its RPM ceiling before the heatsink saturates, limiting peak cooling capacity.
