Compact 80 mm square axial cooler

The OEM Industries 3112KL-04W-B69 is a 12 V DC axial fan built for case and CPU cooling in tight spaces. Its 80 mm square frame fits standard mounting holes and the three-wire connector reports speed to the motherboard. The unit ships new in black with no illumination.

Dual-ball bearing thermals and acoustics

Dual ball bearings support a speed range of 4000 to 4499 rpm, delivering 50 to 55 cfm of airflow at a noise level of 45 to 50 dBA. Current draw is 0.58 A at 12 V, keeping power use low while the bearing design resists wear in continuous operation.

Three-wire speed monitoring only

The bundled three-wire lead provides tachometer feedback so the system can adjust fan curves automatically. No LED lighting, PWM control or mounting hardware beyond the fan body is included, so builders needing variable voltage control or extra screws must source them separately.

Questions about this item

How do I install the 3-wire connector on the 3112KL-04W-B69 and which step is often missed?

Plug the 3-wire connector into a 12 V fan header on the motherboard; the step often missed is setting the header to PWM or DC mode in BIOS so the tachometer wire reports speed correctly.

What maintenance will the 2-ball bearing in the 3112KL-04W-B69 need later?

The dual ball bearing is sealed for life; no lubrication is required, but dust should be blown out of the 80 mm blades every few months to keep airflow near the 50–55 CFM rating.

At what point does the 3112KL-04W-B69 hit its thermal or noise limit under sustained load?

At full 12 V the fan runs 4000–4499 RPM and produces 45–50 dBA; that acoustic level is the first limit reached during continuous operation.
