120 mm Server Cooling Fan

This 120 mm fan runs on 12 V and draws 2.7 A through a 4-pin connector. It spins between 1500 and 2000 rpm using high-precision double ball bearings. The frame measures 120 by 120 by 38 mm and is rated for 100000 hours of operation.

Suitable For High-Airflow Server Chassis

Builders who need 210.38 CFM at 21.60 mmH2O static pressure for dense server racks or Bitcoin miner enclosures will match this specification. Buyers who require lower noise than 25 dB-A or a smaller 25 mm thick frame should consider other models.

4-Pin PWM Power Interface

The four-pin connector delivers PWM speed control and tachometer feedback to the motherboard or fan controller. Verify that the header supplies 12 V at 2.7 A before installation.

Questions about this item

Will the 120mm 38mm 4PIN fan fit alongside my existing 120mm 25mm case fans?

This fan is 38 mm thick versus the common 25 mm, so it needs extra clearance; check your case specs before mounting it next to slimmer fans.

How can I verify the double ball bearing fan is running at the rated 1500-2000 rpm after installation?

Connect the 4PIN header to your motherboard or fan controller, then monitor RPM in BIOS or software; it should read between 1500 and 2000 rpm under load.

Does the package include mounting screws or a 4PIN-to-Molex adapter, or must I buy them separately?

The supplier lists "Package: Yes" but does not detail contents; expect the fan unit only and source screws or adapters separately if your case lacks them.
