80mm 12V PWM case fan

The SXDOOL 3115RL-04W-B76 is an 80mm case fan built around a NMB double ball-bearing motor. It runs on 12V DC and draws 1.60A through a standard 4-pin connector. The 25cm cable supports PWM automatic speed control for system-managed cooling.

Suited for tight 80mm mounts needing high airflow

Builders fitting compact chassis or legacy 80mm brackets will appreciate the 116CFM peak flow. The noise level exceeds 50 dBA at full speed so it is not a fit for silent-focused systems or noise-sensitive workspaces. Users wanting RGB illumination should look elsewhere as this is a non-LED unit.

Sustained output from double ball bearings

The double ball-bearing design with special IC targets 180000 hours MTTF for continuous duty. PWM control lets the motherboard lower RPM under light load to reduce wear and noise. At maximum 6500rpm ±10% the fan maintains the rated 116CFM without throttling.

Questions about this item

What motherboard header is required for the 4-pin PWM connector on this 80mm fan?

A standard 4-pin PWM fan header supplies the 12 V rail and the PWM control signal that the 1.60 A motor needs.

Will the 25 cm cable reach a rear-exhaust header on a full-size ATX board when mounted in an 80 mm rear slot?

The 25 cm lead is designed for short runs such as an 80 mm rear mount to a nearby CPU or chassis fan header; measure your board layout before fitting.

How can I confirm the double ball-bearing motor is spinning at the rated 6500 rpm after installation?

Use BIOS hardware monitor or fan-control software to read the tachometer signal on the 4-pin header; it should report roughly 6500 rpm at full PWM duty.
