Pressure-optimised 120 mm fan for continuous

The ARCTIC P12 PWM PST CO is a single 120 mm case fan built for static-pressure tasks such as heatsinks and radiators. It uses a fluid-dynamic bearing and PWM Sharing Technology to run several fans in sync from one motherboard header. The unit ships with four mounting screws and a 4-pin connector plus passthrough socket.

Suited to builds that need focused airflow through

This model fits users who want quiet, pressure-oriented cooling on CPU coolers or liquid-cooling radiators. It is not intended for buyers who need high-volume airflow for open mesh cases or for systems that require a bundled fan controller or RGB lighting.

Runs at 200 to 1800 RPM with a 0.3 Sone noise floor

Under sustained load the motor maintains efficiency thanks to a modern PWM IC and dual ball bearing rated for five times the life of standard designs. Internal tests at 28 dB(A) show consistent static-pressure delivery without the speed drop-off seen in short-burst operation.

Domande su questo articolo

Does my motherboard need a 4-pin PWM header to run this fan?

Yes, the fan uses a 4-pin PWM connector for power and speed control.

Can I daisy-chain this 120 mm fan with older 3-pin fans using the PST socket?

The 4-pin PST socket passes the PWM signal through, so 3-pin fans on the chain will run at full speed instead of being regulated.

How do I confirm the fan is spinning within its 200-1800 RPM range after installation?

Check the RPM reading in BIOS or monitoring software; it should vary between 200 and 1800 RPM as the PWM duty cycle changes.
