120mm case fan for quiet cooling

The Corn Electronics PC-M120R is a 120mm case fan built for low-noise airflow inside PC cases, CPU coolers and radiators. It uses a hydraulic bearing rated for over 30,000 hours and eight silicone shock-absorbing pads to minimise vibration. The fan connects via a 5V three-pin header. Red illumination comes from 33 LEDs arranged around a light-guide ring.

Sustained-load airflow and acoustics

At a fixed 1200 RPM with a ten-per-cent tolerance the fan delivers steady air pressure through its nine SilentPro blades and surface guide grooves. The hydraulic bearing maintains consistent speed without oil overflow during continuous operation. Acoustic output stays at 19 dBA, a level comparable to quiet breathing, even after extended running periods.

Thermals, noise and power in normal use

The diversion blade design concentrates airflow on the leading edge to improve heat dissipation across radiators and heatsinks. Rubber pads on both sides of the frame suppress chassis resonance. Power draw is limited to the 5V three-pin connection, keeping energy use low while the corona LED ring provides red lighting without additional cables.

Questions about this item

How loud is the PC-M120R at its 1200 RPM operating speed?

The fan produces 19 dBA, which is comparable to normal breathing, making it very quiet for continuous daily use.

What motherboard header does the 5 V 3-pin connector on this fan require?

It needs a standard 5 V 3-pin addressable-RGB header on the motherboard to power both the motor and the red LED lighting.

Will the 120 mm frame and 1200 RPM airflow match an older CPU cooler designed for 120 mm fans?

Yes, the 120 mm dimensions and 1200 RPM speed are standard for legacy coolers, and the eight silicone pads prevent vibration on older mounts.
