120 mm 4-pin ball-bearing fan

This 120 mm frame fan uses a dual ball bearing and a 4-pin PWM connector for speed control. It is built for system integrators and technicians who need a reliable replacement or custom cooling part. The unit ships as a bare fan without heatsink or mounting hardware.

48 V 0.54 A power draw and thermals

Rated at 48 V and 0.54 A, the motor draws modest current while the ball bearing reduces friction heat during continuous operation. PWM control lets the system lower speed at idle, cutting both noise and power draw. No LED lighting means no extra electrical load.

No bundled accessories or software

The package contains only the fan itself; no screws, cables, adapters or software utilities are included. Buyers who need mounting hardware or a fan controller must source those separately. Integrators should verify the 120×120×38 mm dimensions against their chassis clearance before ordering.

Questions about this item

How do I install the 48V 4-pin fan and what step is often missed?

Connect the 4-pin PWM header to a 48V fan controller; the step often missed is verifying the supply delivers 48V at 0.54A rather than a standard 12V header.

What maintenance will the 2-ball bearing fan need later?

The 2-ball bearing design is sealed; no lubrication is required, but dust should be cleared from the 120mm blades and 38mm frame periodically.

What limit appears first during sustained 48V 0.54A operation?

Continuous draw of 0.54A at 48V makes bearing heat the first limit; ensure case airflow keeps the 120x120x38mm housing within its rated temperature range.
