Compact 2.5 cm 5 V case fan

This 2.5 cm case fan operates at 5 V and draws 0.18 A, making it suitable for tight chassis spaces or targeted component cooling. It is built around the NMB 1004KL-01W-B50 motor for reliable airflow in small-form-factor builds.

Thermals noise and power draw

The low 5 V 0.18 A rating keeps power consumption minimal while delivering focused airflow for confined areas. Expect quiet operation appropriate for noise-sensitive environments such as HTPCs or compact workstations.

Questions about this item

How do I mount the 2.5 cm fan and what is the common mistake with the 5 V supply?

Secure the 2.5 cm frame with four screws matching the 1004 hole pattern, then plug the two-wire lead into a 5 V header; the frequent error is reversing polarity which stops the motor.

When will the NMB 1004KL-01W-B50 need replacement and what should I check?

Expect many years of continuous use; inspect annually for bearing noise or reduced airflow and replace if the 0.18 A draw rises or the rotor stalls.
