OEM Industries UF-133823 135mm Ball Bearing Fan

This 135mm ball bearing fan from OEM Industries operates directly from AC 230V mains at 0.15A across 50/60Hz. It draws 24/23W and uses a simple two-wire power connection. The unit is intended for case or enclosure cooling where a standard mains supply is available and no PWM control is required. Black housing blends with typical chassis interiors.

Practical limits of AC mains power

Because the fan runs on fixed AC voltage, speed cannot be adjusted by the motherboard or a fan controller. It will spin at full speed whenever the circuit is live, producing constant airflow and constant noise. The two-wire lead provides no tachometer signal, so the system cannot monitor rotation or trigger alerts if the fan stops. Builders needing variable speed or RPM feedback must choose a different interface.

Ball bearing durability and mounting implications

The ball bearing design handles continuous 24/7 operation with less wear than sleeve alternatives, suiting servers or always-on workstations. The 135mm frame fits standard mounting holes for that size, but the AC plug or flying leads require access to a mains socket or terminal block inside the enclosure. No LED lighting is present, keeping visual distraction to a minimum in professional environments.
