ASUS Prime MR120 ARGB fan overview

The ASUS Prime MR120 is a single 120mm case fan with an extra-thick 28mm frame. It targets builders who want stronger static pressure and addressable RGB lighting in a black finish. The sleeve bearing keeps acoustic output low at 21 dBA while the 4-pin PWM connector allows motherboard speed control up to 1999 RPM.

PWM control and 4-pin connector limits

Speed is regulated through a standard 4-pin PWM header so the motherboard can vary RPM between 1600 and 1999. Without a dedicated fan controller in the box the fan relies entirely on the header or a hub for power and signal. The 1.7 mmAq pressure rating suits radiators or restrictive meshes but offers no headroom beyond the stated curve.

Clearance and orientation check before ordering

Verify that your case or radiator can accommodate a 28mm thick fan at each mounting point. The dual-sided frame lighting requires visible fan faces to be effective so solid front panels or tight side panels may hide the effect. Confirm the motherboard has a 5V ARGB header or a compatible controller for Aura Sync synchronization.

Questions about this item

Should I pick the black or white version of the 28mm Prime MR120?

Both colours share the same 28mm frame, 20 ARGB LEDs and 1600 RPM PWM range, so choose the finish that matches your build theme.

What does the 1.7 mmAq static pressure mean for my radiator or heatsink?

The 1.7 mmAq rating lets the fan push air through dense fins on radiators or tower coolers while staying at 21 dBA.

How does the 4-pin PWM connector control the 1600-1999 RPM range?

The motherboard varies voltage on the fourth wire to keep the fan between 1600 and 1999 RPM based on temperature curves.
