ARCTIC

ARCTIC P12 PWM PST CO 120 mm Case Fan

SKU CH-44P5-M7T4R

A 120 mm case fan optimised for static pressure with PWM sharing, dual ball bearing for 24/7 operation, 200–1800 RPM speed range and 56.3 CFM airflow

  • Pressure-optimised design delivers 56.3 CFM airflow for dense radiators
  • PWM sharing technology lets multiple fans run from one header
  • Dual ball bearing rated for 24/7 continuous operation
  • Motor runs 10 °C cooler for four-times longer service life
  • 3 sone noise level at 1800 RPM keeps system quiet

Pressure-Optimised 120 mm Case Fan

The ARCTIC P12 PWM PST CO is a 120 mm case fan designed for focused airflow and high static pressure. It uses a 4-pin PWM connector and supports PWM Sharing Technology to synchronise multiple fans from a single header. A Japanese dual ball bearing enables continuous 24/7 operation. The motor runs at lower coil temperature for extended service life.

Suited for Radiators and Restricted Airflow

Builders who need strong static pressure for radiators, dense mesh or dust filters will benefit from the pressure-optimised blade design. The fan speed range spans 200 to 1800 RPM with a 0 RPM mode below 5 % duty cycle. Systems that prioritise maximum airflow volume over pressure or require a different frame size should consider other options.

Sustained Load Behaviour

Under continuous load the motor maintains efficiency through a Neodym-Iron-Boron magnet ring that reduces coil temperature by roughly 10 °C. At 1800 RPM the fan delivers 56.3 CFM or 95.65 m³/h at 0.3 Sone. The dual ball bearing and lower operating temperature support a service life approximately four times longer than previous designs.

Questions about this item

What motherboard header is needed to control the 4-pin PWM fan speed from 200 to 1800 RPM?

A standard 4-pin PWM fan header on the motherboard provides both power and speed control for the full 200–1800 RPM range.

Can multiple P12 PWM PST CO fans share one motherboard header using the PWM Sharing Technology?

Yes, the PWM Sharing Technology (PST) allows several fans to be daisy-chained so one 4-pin header controls all their speeds together.

How can I confirm the fan is running at its rated 56.3 CFM and 0.3 Sone at 1800 RPM after installation?

Use BIOS or monitoring software to verify the fan reports 1800 RPM; at that speed the airflow reaches 56.3 CFM and the noise level is 0.3 Sone.
