Laptop CPU Cooling Fan for HP 4540S Series

This new replacement cooler fits HP 4540S, 4740S, 4745S, 4440S, 4441S, 4445S and 4446S notebooks. It is designed for owners who need to replace a worn or faulty original fan. The four-line connector matches the motherboard header on these specific models. Buyers with other HP series or different laptop brands cannot use this part.

Thermals, Noise and Power Draw

The fan restores factory airflow to the CPU heatsink, helping the processor maintain normal operating temperatures during typical workloads. Power consumption stays within the laptop's original design limits for the cooling subsystem. Acoustic output is comparable to the stock cooler when running at standard speeds. No specifications for maximum RPM, decibel levels or wattage are provided by the supplier.

Questions about this item

How do I install the 4-line connector on my HP 4540S, and what step do people often miss?

Align the 4-line connector with the motherboard header and press straight down until it clicks; the step many miss is routing the cable clear of the fan blades so it cannot snag when the fan spins up.

What maintenance will this cooling fan need later?

Blow dust from the heatsink fins and fan blades with compressed air every few months; if bearing noise appears or airflow drops, replace the whole fan unit.
