OEM Industries 1225L12S 120mm 2-Pin Sleeve Fan

120 mm 2-Pin Sleeve Fan

This 120 mm square fan uses a sleeve bearing and a 2-pin connector to deliver basic airflow for CPU air coolers or case ventilation. It runs on 12 V at 0.4 A and has no LED lighting. The simple two-wire design suits builds that only need on/off power without speed reporting.

25 mm thick, 0.4 A headroom

At 25 mm thick the fan fits standard 12025 mounting points and draws a modest 0.4 A, leaving ample headroom on a typical 12 V rail. The sleeve bearing keeps noise low at modest speeds, but sustained high-RPM operation will wear the bearing faster than a ball or fluid-dynamic alternative. It handles everyday cooling loads; it runs out when continuous maximum static pressure is required.

Replaces worn 2-pin 120 mm fans

This unit directly replaces a failed or noisy 2-pin 120 mm sleeve-bearing fan in an existing cooler or chassis. The jump is worth it when the original fan has developed rattle, reduced airflow, or complete failure and the motherboard header remains a 2-pin type. Builders who need PWM speed control or a tachometer signal should look for a 3-pin or 4-pin model instead.
