Compatible Laptop Models

This replacement CPU cooling fan fits Lenovo G400S, G405S, G500S, Z501 and Z505 notebooks. It is a new component intended for repair or maintenance of those specific models. The four-pin connector matches the original motherboard header. Buyers with different laptop series will need a different part.

Four-Pin Power and Control

The fan uses a standard four-pin interface that supports PWM speed regulation by the system BIOS. This allows the laptop to adjust fan speed based on processor temperature, balancing airflow with acoustic output. No specifications for noise level, airflow or power consumption are provided by the supplier.

Questions about this item

How do I install the 4-pin connector on my Lenovo G500S and which step is often missed?

Align the keyed 4-pin plug with the motherboard header, press straight down until it clicks, then route the cable clear of the fan blades — the step most people skip is verifying the latch is fully seated.

What maintenance will this CPU fan need on a Lenovo Z501 over time?

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