150 mm DC blower for server and inverter cooling

This 150 mm DC blower uses a 2‑ball bearing and a 4‑pin 12 V connector drawing 1.7 A. It is built as a fan‑only unit for chassis or server inverter cooling where directed airflow is required. The black housing matches standard industrial aesthetics. Buyers who need a traditional heatsink‑and‑fan CPU cooler should look elsewhere.

Sustained airflow with 2‑ball bearing reliability

The 2‑ball bearing design maintains consistent rotation during continuous duty cycles typical of server and inverter environments. Four‑wire PWM control lets the system adjust speed to thermal load without the wear associated with sleeve bearings. No LED lighting means no extra power draw or visual distraction in rack installations.

Verify 150 mm × 38 mm clearance and 4‑pin PWM header

Confirm the mounting area accommodates a 150 mm by 38 mm frame before ordering. The unit requires a 4‑pin PWM header capable of supplying 12 V at 1.7 A. Systems limited to 3‑pin voltage control or smaller fan cut‑outs will not support this blower.

Questions about this item

How much noise and heat does the 150mm blower produce when running continuously at 12V 1.7A?

The 2-ball bearing NMB 150*38mm blower draws 1.7A at 12V and uses a 4-pin connector for PWM speed control, so fan speed — and therefore noise and airflow — can be adjusted by the motherboard or fan controller to match the thermal load.

What power connector and voltage source does the BG1504-B045-POL need to operate?

It requires a standard 4-pin PWM header supplying 12V DC; the 4-wire interface carries power, ground, tachometer feedback and PWM control signal.

Will the 150mm frame and 4-pin PWM interface work with my older motherboard that only has 3-pin headers?

The 4-pin plug fits a 3-pin header mechanically, but PWM speed control will be lost and the fan will run at full 12V speed; a 4-pin header or external PWM controller is needed for variable speed.
