NMB 3110RL-04W-B79 80 mm case fan

This 80 by 80 by 25 millimetre fan runs on 12 volts and draws 0.44 amps. It uses a three-wire connection and ball-bearing construction for continuous airflow inside a computer chassis. The unit is suited to builders who need a compact cooling component for tight spaces. It will not suit buyers who require a larger frame size or higher static pressure for dense radiators.

Simple three-wire installation

Mount the fan using standard 80 millimetre screw holes and connect the three-wire header to the motherboard or fan controller. Ball bearings reduce friction wear compared to sleeve types, extending service life in continuous operation. The only common issue is ensuring the connector orientation matches the header pinout to avoid a non-spinning fan. No special tools or adapters are required for a standard fit.

Questions about this item

How can I confirm the fan is spinning correctly after connecting the 3-wire connector to a 12V header?

The 3-wire connector carries a tachometer signal; plug it into a motherboard fan header and verify RPM in BIOS or monitoring software while the system runs.

What comes in the box and are mounting screws or a power adapter included?

The package contains the 80 mm square frame fan with ball bearing and 3-wire lead; mounting screws and any adapter cables are not included and must be sourced separately.
