120×120×25 mm 12 V chassis fan

This 120 mm case fan fits standard chassis and power-supply mounts with a 25 mm thickness. It runs on a 12 V two-wire supply, making it a direct drop-in for many desktop and server enclosures. The compact frame leaves clearance for tight component layouts.

Replaces worn or noisy two-wire 120 mm fans

Swap it in when an existing 120×25 mm 12 V fan fails or becomes loud, restoring airflow without rewiring. The two-wire design means no speed reporting or PWM control, so it suits constant-speed cooling roles rather than variable-speed curves.

Questions about this item

What mounting hole spacing does the 120 mm frame use?

The fan follows the standard 120 mm square pattern with holes centred on the four corners of the 120 mm frame.

How is the 2-wire power lead connected?

Plug the 2-wire connector into a 12 V fan header; the tachometer pin is absent so speed reporting will not function.
