Compact 80 mm case fan

The OEM Industries 3108NL-04W-B30 is an 80 mm ball-bearing fan designed for general case airflow. It runs on 12 V at 0.19 A and connects with a two-wire lead. The black frame and lack of LEDs keep the appearance neutral inside any chassis.

Suits basic cooling upgrades

Builders replacing a worn 80 mm exhaust or intake fan will find a direct mechanical match. Systems that require PWM speed control, higher static pressure for dense heatsinks, or larger mounting patterns should look elsewhere.

Two-wire power connector

The fan uses a simple two-wire interface, so speed is fixed at full voltage unless the motherboard or controller supports voltage regulation. Verify that your header can drive a 12 V 0.19 A two-wire device before purchasing.

Questions about this item

What power connector does the 3108NL-04W-B30 need from my power supply?

The fan uses a simple two-wire lead that connects directly to a 12 V supply rail or a standard two-pin header on the motherboard or fan controller.

Will this 80 mm ball-bearing unit fit the screw pattern of my older 8020-style chassis fan mount?

Yes, the 80 mm frame follows the common 8020 mounting hole spacing so it drops into legacy case or heatsink brackets without adapters.

How can I confirm the 3108NL-04W-B30 is spinning at the correct speed after installation?

Check the motherboard BIOS or a hardware-monitoring utility; it should report a steady RPM reading for the connected header, and you should feel consistent airflow from the black blades.
