NMB 9.7 cm 24 V 4-wire case fan

This NMB case fan measures 9.7 cm and runs on a 24 V supply with a 1.1 A current draw. The four-wire interface provides PWM speed control for precise airflow management. It is supplied new and carries the BG0903-B056-POS model designation.

Suited for systems with 24 V fan headers

This unit fits builds that use a 24 V four-pin fan header and need a 9.7 cm frame. Buyers whose boards only provide a lower-voltage header or a three-pin connector cannot use this fan. Those requiring a different frame size or airflow rating should consider other options.

Questions about this item

How much noise and heat does the BG0903-B056-POS generate when running continuously at 24 V?

The fan draws 1.1 A at 24 V and spins at 9733 RPM, so expect audible airflow noise and moderate heat from the motor during all-day use.

What connector and voltage source does the 4-wire BG0903-B056-POS require to operate?

It needs a 24 V PWM header with a standard 4-pin fan plug; the motherboard or fan controller must supply 24 V and a PWM signal for speed control.
