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.

Preguntas sobre este artículo

How can I confirm the fan is running correctly after installation?

Connect the 4 Pin connector to the motherboard header and verify the fan spins at 12V with a 3.0A draw through BIOS or monitoring software.

What comes in the box and what must I source separately?

The package includes the NIDEC 12038 square cooler unit only; mounting screws, thermal paste and any additional case brackets are not included.

Which version of this cooler should I select for a 120 mm server fan slot?

Choose the V12E12BS2B5-07A021 HF104-A00 model with 12V 3.0A 4 Pin wiring to match the 12038 12*38mm form factor.
