Replacement Fan for Lenovo B465 G465 G470

This 5 V 0.50 A four-pin fan is built as a direct drop-in cooler for Lenovo B465C, G465C, G465 and G470E notebooks. It draws power from the standard motherboard header and requires no extra wiring or adapters. The black housing matches the original chassis finish. Owners of those specific models can restore stock cooling performance immediately.

Suitable for Lenovo B465 G465 G470 owners only

Technicians repairing the listed Lenovo laptops will find the correct connector pinout and voltage already matched. Builders working on any other brand, desktop board, or newer Lenovo chassis should look elsewhere because the mounting holes and cable length are tailored to the 465 and 470 series. The unit is a bare fan without heatsink or PWM controller.

Handles standard CPU thermal loads in target laptops

At 5 V and 0.50 A the motor delivers the airflow Lenovo specified for the B465C, G465C, G465 and G470E platforms. It keeps temperatures in check during typical office workloads and video playback. Sustained heavy compiles or gaming sessions may push the single fan beyond its design envelope, so users expecting higher dissipation should consider a full assembly upgrade.

Questions about this item

Does the DFS491105MH0T need a 4-pin motherboard header to run?

Yes, the fan uses a 4-pin connector that plugs directly into a 4-pin CPU fan header on the motherboard.

Will this cooler fit a Lenovo G465 that already has the original heatsink?

The fan is listed for the G465, G465C, B465C and G470E models; it mounts on the existing heatsink used in those laptops.

How can I confirm the DFS491105MH0T is spinning at the correct speed after installation?

Check the fan RPM in BIOS or monitoring software; it should report a steady speed because the 4-pin PWM connection allows the board to control it.
