Montech RX120 PWM Computer case Fan 12 cm White 3 pc(s)

The Montech RX120 PWM Computer case Fan 12 cm White 3 pc(s) is a set of three 120 mm case fans designed to provide efficient airflow for PC chassis. Each fan uses a rifle bearing and supports PWM control, allowing automatic speed adjustment between defined minimum and maximum rotational speeds. The white finish integrates with light-themed builds and helps maintain stable internal temperatures by moving air through intake and exhaust positions.

Advantages

These 120 mm fans offer a balance of airflow and acoustic performance thanks to their specified rotational speed range. PWM control enables precise fan speed regulation according to motherboard or fan controller signals. The rifle bearing provides reliable operation and a useful service life for typical desktop use. The pack of three fans simplifies upgrading or outfitting multiple fan mounts in a single purchase.
