120 mm ball-bearing case fan

The OEM Industries 4710NL-04W-B50 is a 120 mm square frame fan built with a ball bearing for continuous operation. It connects through a standard two-pin header and draws point seven four amps at twelve volts. The black housing contains no lighting and is intended as a direct replacement for NMB 12025 units in chassis or heatsink applications.

Two-pin power connector requirement

This cooler uses a two-wire, two-pin plug that supplies constant twelve-volt power without pulse-width-modulation speed control. Builders whose motherboards or fan controllers provide only three-pin or four-pin headers will need an adapter or a dedicated two-pin source. The fan runs at full speed whenever powered, so it suits systems that do not require variable RPM.

Ball bearing airflow and acoustics

The ball bearing design sustains steady airflow over long periods with minimal friction increase. At the rated current the motor draws modest power while delivering consistent static pressure through heatsink fins. Expect a constant audible hum at full voltage; systems needing silent or thermally managed operation should consider speed-controlled alternatives.

Questions about this item

What does the 12V 0.74A rating mean once the fan is installed in a PC?

The fan will draw up to 0.74 amps from the 12 volt rail, consuming roughly nine watts while running at full speed.

How does the 2-pin power connector limit control of the 4710NL-04W-B50?

A 2-pin connector supplies constant voltage, so the fan always spins at its fixed maximum speed with no PWM or voltage regulation.

What clearance does the 120mm by 25mm frame need to mount in a case?

The square frame measures 120 millimetres on each side and is 25 millimetres thick, requiring that much open space at the mounting point.
