80 mm double-ball server fan

The NMB 3112KL-04W-B69 is an 80 mm case fan built with a double ball bearing for extended service life in continuous operation. It runs on 12 V at 0.58 A and connects through a standard three-pin header. The 20 cm lead wire reaches most motherboard fan headers without extension cables.

Replaces worn 8032 frame fans

This unit fits the 80×80×32 mm footprint used in many legacy servers and compact workstations. The jump is worthwhile when an existing sleeve-bearing fan develops noise or fails to spin up reliably. The double ball bearing tolerates higher ambient temperatures and maintains consistent speed reporting through the third wire.

Suits maintenance on rack gear and tight builds

Technicians servicing 1U appliances or small-form-factor chassis will find the exact mounting holes and connector match they need. Builders who require PWM speed control or a larger frame for higher static pressure should look at a different fan.

Questions about this item

Will the 80×80×32 mm frame fit my standard 80 mm mounting holes?

Yes, the 80 mm square frame with 32 mm thickness matches the common 80 mm fan mounting pattern used on cases and heatsinks.

How do I connect the 3-pin lead to my motherboard, and what mistake should I avoid?

Align the keyed 3-pin connector with the motherboard header tab; forcing it backwards bends pins and disables the speed-alarm signal.

When will the double ball bearing need replacement?

Double ball bearings typically run for tens of thousands of hours; replace the fan if noise increases or the speed-alarm reports a drop.
