OEM Industries AD1248HB-Y56 120mm 2 Ball Fan

120 mm dual-ball bearing fan

The OEM Industries AD1248HB-Y56 is a 120 mm cooling fan built with a dual-ball bearing for extended service life. It operates on a 40 V supply drawing 0.13 A through a standard three-wire power connector. The unit ships in black without any integrated lighting.

Sustained-load behaviour

Dual-ball bearings maintain consistent rotational stability during continuous operation, reducing the risk of lubricant migration that can affect sleeve designs. The three-wire interface supplies a tachometer signal so the host system can monitor speed in real time. Steady airflow is preserved over long duty cycles without performance decay.

Thermals noise and power

At 0.13 A the fan draws minimal power while delivering targeted airflow for CPU cooler stacks. Bearing construction keeps acoustic output low and predictable under normal case pressure. The absence of LEDs eliminates extra heat sources and visual distraction in noise-sensitive builds.
