120 mm 48 V dual-ball bearing fan

This 120 mm cooling fan operates on a 48 V supply and draws 0.95 A through a four-wire connector. The dual-ball bearing design targets systems that need reliable airflow at higher voltage rails. It is intended for technicians who service industrial or server-grade CPU air coolers requiring this specific electrical profile.

Dual-ball bearing and four-wire control

Two ball bearings reduce friction and extend service life compared with sleeve alternatives, supporting continuous duty in demanding thermal environments. The four-wire interface carries power, ground, speed reporting and PWM control, allowing the host system to modulate fan speed based on temperature feedback from the onboard thermistor.

Fan-only package with thermistor feedback

The box contains the fan unit alone; no mounting brackets, screws or adapters are included, so installers must reuse or source compatible hardware. The integrated thermistor enables automatic speed regulation without external sensors, simplifying wiring in replacement scenarios. Buyers who need a complete cooler assembly or low-voltage 12 V operation should look elsewhere.

Questions about this item

Does the 4-pin connector support PWM speed control and tachometer feedback?

Yes, the four-wire interface provides PWM control and a tachometer signal so the motherboard can regulate speed and monitor RPM.

Will the 120 mm frame and 38 mm thickness fit standard 120 mm mounting holes?

The fan uses the common 120 mm square frame with 38 mm depth, matching typical 120 mm case and radiator mounting patterns.

How do I connect the four wires correctly, and what mistake should I avoid?

Plug the 4-pin header into a PWM fan socket aligning the key; do not force it into a 3-pin header or you will lose speed control.
