120 mm 200 CFM dual-ball-bearing fan

This 120 mm by 38 mm DC fan moves 200 CFM at 4000 RPM using a dual ball bearing. It draws 1.4 A at 12 V with a 36 W input and connects through a standard 4-pin Molex power plug. The operating voltage range spans 7 to 13.2 V.

Suited for high-airflow server or mining rigs.

The 59 dBA maximum noise level makes this fan appropriate for server chassis, mining rigs or industrial ventilation where raw airflow matters more than acoustics. Builders who need a silent or low-noise environment should look at lower-speed alternatives. The metal finger guard adds safety in open-frame or high-traffic installations.

36 W power draw per fan at 12 V

Each unit consumes 36 W at the rated 12 V, so the power supply must deliver enough 12 V current for every fan installed. The 4-pin Molex connector draws directly from the PSU without motherboard speed control. Verify that your PSU has sufficient Molex connectors and 12 V capacity before adding multiple fans.

Questions about this item

Does my case have the 120mm x 38mm mounting space and a free 4-pin Molex connector for this fan?

The fan measures 120mm x 120mm x 38mm and draws 1.4A at 12V through a 4-pin Molex connector, so your case needs that clearance and a spare Molex lead from the power supply.

Will the 4000 RPM speed and 59dBA noise overwhelm older components on the same Molex rail?

Each fan pulls up to 3.0A peak, so a shared Molex rail must handle that surge; the 59dBA output is loud, so isolate vibration with the included metal grills and screws to protect aging drives.

How can I confirm the fans are spinning at the rated 4000 RPM after installation?

Connect the 4-pin Molex, power on, and check BIOS or fan-control software for a reading near 4000 RPM; the strong airflow and audible 59dBA hum also confirm full-speed operation.
