OEM Industries V12E12BS2B5-07A021 HF104-A00 12038 12V 3.0A 4 Pin CPU cooler

Square 120mm Server Fan

This NIDEC 12038 square cooler measures 120mm across and fits standard 120mm mounting holes in server chassis or workstations. The unit is a fan-only assembly without heatsink fins, so it serves as a direct-replacement airflow component for compatible CPU cooler brackets or case positions. It ships new in black with a 4-pin PWM connector for automatic speed control.

4-Pin PWM Installation

The four-wire connector plugs directly into a motherboard or fan-controller header keyed for 12V 3.0A operation, requiring no adapters or soldering. Installers must verify that the header can supply the rated current, as undersized headers may trigger protection shutdowns or erratic speed curves. The square 120x38mm frame uses standard screw spacing, but clearance around nearby components should be checked before mounting.

Sustained 12V 3.0A Operation

At the full 12V 3.0A rating the fan delivers continuous airflow suited to server environments where thermal loads remain high for extended periods. PWM control allows the speed to scale with temperature, reducing acoustic output during lighter workloads while maintaining headroom for prolonged heavy compute tasks. The brushless motor design supports 24/7 duty cycles without the performance drop-off seen in short-burst testing.
