Replacement CPU fan for discrete graphics laptops

This new cooling fan fits HP Pavilion 15-CS series notebooks that use a discrete graphics card. It replaces the original part coded L25585-001 and matches the mounting points shown in the product images. Buyers with integrated-graphics models or other HP series should not order this part.

Thermals noise and power draw

The fan draws power from the laptop motherboard header and spins under firmware control to cool the CPU and discrete GPU. Acoustic output varies with workload and the system fan curve. No independent thermal or power measurements are supplied.

Compatibility list decides fit

Supported models include Pavilion 15-CS0073CL, 15-CS1000 series, 15-CS1063CL, 15-CS1065CL, 15-CS2000 series, 15-CS2073CL and 15T-CS series. Verify the exact model number and compare the connector and screw layout with the photos before purchasing.

Questions about this item

How do I install the CPU fan for discrete graphics on my Pavilion 15-CS1000 and what step is often missed?

Remove the bottom cover, disconnect the battery, unscrew the old fan assembly, fit the new L25585-001 unit, reconnect its cable, then reapply thermal paste on both CPU and GPU dies before reassembly.

What maintenance will this replacement fan need later?

Blow dust from the heatsink fins and intake vents every few months with compressed air; if bearing noise or RPM drop appears, replace the fan again using the same L25585-001 part.

What limit appears first when the laptop runs sustained loads with this fan?

The single fan must cool both CPU and discrete GPU, so thermal throttling on either chip will occur before the fan reaches its maximum speed.
