NMB-MAT 80×25 mm axial fan

The NMB-MAT 3110KL-04W-B79 is a 12 V axial fan measuring 80 mm by 80 mm by 25 mm. It spins at 4800 RPM and delivers 49.6 CFM of airflow while producing 45.6 DBA of noise. The unit draws 0.38 A and operates within a 6.0 V to 13.8 V range.

Suitable for Cisco 2821 switch cooling

This fan is built as a direct replacement for the Cisco 2821 switch and fits other equipment that accepts an 80 mm frame with the same voltage and current profile. It is not intended for builds that require a larger frame, lower acoustic output, or higher static pressure than the listed 45.6 DBA specification allows.

4800 RPM speed rating

The 4800 RPM rating determines the airflow and noise level you will observe in service. Verify that the target device can accommodate this speed and the associated 49.6 CFM output before installation.

Questions about this item

At what speed does the 3110KL-04W-B79 reach its airflow limit under sustained use?

The fan runs at 4800 RPM and delivers 49.6 CFM continuously within its 6.0 V to 13.8 V operating range.

What noise and heat output should I expect when the 3110KL-04W-B79 runs all day?

It produces 45.6 DBA and draws 4.56 W at 12 V, so heat and noise stay constant at that level.

Which connector does the 3110KL-04W-B79 need from my existing wiring to work?

The supplied title lists a 4-wire lead; you need a matching 4-pin header or adapter on your system.
