Replacement CPU fan for Lenovo G-series

This new 4-pin cooling fan fits Lenovo G470, G474, G475, G570 and G575 notebooks. It is designed as a direct replacement for the original CPU air cooler in those models. The part is supplied in new condition and ready for installation. It restores proper thermal management when the original fan fails or becomes noisy.

Connector and model compatibility

The cooler uses a 4-pin power connector that must match the motherboard header on the supported Lenovo models.

Verify the exact model number before ordering.

Questions about this item

What does the 4-pin connector mean when the fan is installed in a Lenovo G470?

The 4-pin connector allows the motherboard to control fan speed precisely through PWM, so the cooler runs quietly at low load and ramps up only when the CPU temperature rises.

Which interface does this cooler use and what does it limit in practice?

It uses a standard 4-pin PWM header, which limits control to motherboards that provide a matching 4-pin CPU fan socket; 3-pin headers will run the fan at full speed without speed regulation.
