120mm Ball Bearing Cooling Fan

This 120mm fan uses a dual ball bearing for reliable airflow in CPU air coolers. It operates at 24V with a 0.23A draw and connects via a three-wire power connector. The black frame measures 80 by 80 by 25mm and carries the NMB-MAT 3110KL-05W-B89 model designation. It is sold new as a standalone fan unit without LED lighting.

Suited for 24V three-wire headers

Builders who need a 24V 120mm replacement with a three-wire connector and ball bearing durability will find this unit matches those requirements. Systems that rely on 12V power, four-pin PWM control or smaller 80mm mounting holes cannot use this fan without modification. Buyers who want integrated lighting or a different voltage should look at other options.

24V 0.23A three-wire specification

The 24V 0.23A rating combined with the three-wire connector is the single specification that determines whether this fan fits a given header and power budget. Verify that the target cooler or chassis provides a 24V three-wire header before purchase. No other voltage or pin configuration is supported by this model.

Questions about this item

Which fan size should I choose between the 80 mm and 120 mm versions?

The product specifications list the fan size as 120 mm, so this is the only size available for this model.

What does the 0.23 A current rating mean when the fan is installed in a system?

At 24 V the motor draws 0.23 A, which determines the power the cooler must supply and the speed the fan will run at.

What does the three‑wire connector provide for speed control?

The three‑wire connector supplies power, ground and a tachometer signal so the motherboard can monitor fan speed.
