80 mm dual ball case fan

This 80 mm case fan uses a dual ball bearing and a 4-pin connector for speed control. It draws 0.36 A and fits the standard 80 by 80 by 20 mm mounting pattern. The 3108NL-04W-B59 model is built as a direct replacement for NMB 8020 units.

Who this does not suit

Builders who need a larger frame size or higher airflow than this 80 mm design provides should look elsewhere. Systems requiring a 3-pin voltage-controlled header will not match the 4-pin PWM connector. Users who prefer sleeve or fluid dynamic bearings may choose a different bearing type.

Questions about this item

How is the 4-pin connector installed and which orientation step is often missed?

Align the 4-pin plug with the motherboard header so the keyed tab matches the slot; the step people miss is forcing it in upside-down, which bends the pins.

What maintenance will the dual ball bearing assembly need later?

Dual ball bearings are sealed and require no lubrication; replacement is only needed if the fan develops audible rumble or stops spinning.
