Pressure-optimised 120 mm case fan

The ARCTIC COOLING P12 PWM is a single 120 mm case fan built for static-pressure tasks. It targets builders who need focused airflow through heatsinks, radiators or partially obstructed vents. The white and transparent frame suits colour-coordinated builds. It is not for users who need a multi-fan kit or an integrated fan controller in the box.

PWM speed range and airflow limits

The fan runs from 200 to 1800 RPM and delivers 56.3 CFM at full speed. The four-pin PWM connector allows the motherboard to vary speed automatically, but the minimum speed is fixed at 200 RPM so the fan never stops completely. Maximum noise is rated at 0.3 Sone. There is no external speed switch or software profile beyond the motherboard curve.

Fluid Dynamic bearing and mounting practicalities

A Fluid Dynamic bearing supports the quiet motor and long-term consistency. The 25 mm thickness fits standard 120 mm mounting points and the package includes four screws for direct case or radiator installation. No rubber anti-vibration mounts or daisy-chain cables are supplied. The white and transparent blades show dust more visibly than darker colours.

Questions about this item

Is the 56.3 CFM airflow enough for a CPU radiator or heatsink?

The fan is optimised for static pressure and rated at 56.3 CFM, making it suitable for heatsinks, radiators and partly covered vents.

What does the 0.3 Sone noise level mean in practice?

At 0.3 Sone the fan is very quiet; the PWM signal lets the motherboard keep speeds low during light loads and ramp up to 1800 RPM only when needed.

Will the 4-pin PWM connector work with my motherboard fan header?

Yes, the 4-pin connector provides standard PWM control so the board can vary speed between 200 and 1800 RPM automatically.
