120mm PWM case fan

The Cooler Master MF120 Lite is a single 120mm fan built for case, liquid-cooler or air-cooler mounting. Its 4-pin PWM connector lets the motherboard vary speed between 650 and 1750 RPM. The sleeve bearing and non-LED black finish suit builders who want simple airflow without lighting.

Hybrid frame and blade design

A revised curved blade profile and hybrid PBT frame are intended to balance airflow and structural stability. Four mounting screws are included for standard 120mm hole patterns. The 25mm thickness fits typical case and radiator positions without special brackets.

Thermals, noise and power

At full speed the fan moves 70.5 CFM with 2 mmH2O static pressure while producing 30 dB(A). Lower PWM duty cycles reduce both airflow and noise for quieter operation. The 4-pin header draws minimal power from the motherboard fan circuit.

Questions about this item

What speed range does the 4-pin PWM connector actually allow on this MF120 Lite?

The 4-pin PWM header lets the fan run from 650 to 1,750 RPM, so the motherboard can tune speed anywhere in that range for noise or airflow.

Will the 25 mm thickness and 120 mm frame fit my case or cooler mounting holes?

Yes, the fan measures 120 x 120 x 25 mm, matching the standard 120 mm hole pattern used on cases, radiators and air coolers.

How do I install the MF120 Lite and what step do people often miss?

Fasten the four included screws through the frame into your case or cooler; the step often missed is setting a PWM curve in BIOS so the fan does not stay at minimum 650 RPM under load.
