What this fan fits

This EN-Labs 4LAYLED12025MX is a 120mm case fan with a 25mm thickness and eleven blades. It targets builders who want a single cooling unit that adds multi-color LED lighting while moving 50-55 CFM at 28 dBA. The hydraulic bearing is rated for 30,000 hours of operation.

Connector and speed limits

Power comes from either a motherboard 3-pin header or a Molex 4-pin 12 VDC plug, so fan speed is controlled by voltage rather than PWM duty cycles. The motor runs at 1100 RPM with a ten-percent tolerance, which fixes the airflow and noise output within a narrow band. Systems that rely on 4-pin PWM headers for dynamic curves will not gain automatic speed scaling from this unit.

Upgrade context

The fan replaces older sleeve-bearing or non-LED 120mm units that run louder or lack lighting. The jump is worth it when a build needs quieter 28 dBA acoustics, a 30,000-hour bearing life, and rainbow illumination without adding a separate LED strip. It does not suit setups requiring PWM control, higher static pressure, or speeds above 1100 RPM.

Questions about this item

What do the 3-pin and 4-pin connectors on the EN-Labs 4LAYLED12025MX actually control?

The 3-pin connector supplies 12 V and a tachometer signal so the motherboard can monitor the 1100 RPM speed; the 4-pin Molex connector provides the same 12 V directly from the PSU without speed reporting.

How loud is 28 dBA from this 120 mm fan inside a typical case?

At 28 dBA the fan is barely audible over a quiet room; in a closed chassis it blends into background noise while still moving 50 to 55 CFM of air.

Does the 4-pin Molex connection limit the fan to a fixed 1100 RPM?

Yes — the Molex 4-pin supplies constant 12 VDC, so the fan runs at its rated 1100 RPM ± 10 % with no PWM speed control.
