The ARCTIC P12 Pro PST CO is a 120 mm PWM case fan for PC builders who need to manage airflow through a radiator, mesh filter or perforated panel. Its single-fan format suits a new build or a replacement fan in a compatible case or cooling setup.

High static pressure helps the fan move air through restricted spaces. PWM control lets a compatible motherboard adjust the speed, while the PST connector lets you synchronise multiple fans from one header. Its dual ball bearing is designed for durability at high rotational speeds, making this model suitable for continuous operation. The fan runs from 600 to 3000 rpm and stops below 5% PWM. At maximum speed it delivers 77 cfm of airflow and 6.9 mmH₂O static pressure.

Key features

• 120 mm frame for compatible case, radiator and cooler mounting positions.
• High static pressure supports airflow through radiators and other restrictive panels.
• PWM speed control adjusts fan operation through a compatible motherboard header.
• PST pass-through connector supports synchronised control of multiple fans from one header.
• Dual ball bearing design supports durability at high rotational speeds.
• Automated balancing is designed to support precise and smooth operation.
• Zero rpm operation below 5% PWM can stop the fan at low control signals.

Compatibility

Check that your case or radiator has a 120 mm mounting position and that your motherboard provides a compatible fan header. The fan uses a 4-pin fan plug and a 4-pin socket; a 3-pin socket can connect to a 4-pin plug, but PWM control will not be available. If connecting several fans, check the header’s current capacity and your motherboard specifications. Good to know: the package is a single fan with four mounting screws; check that the mounting position and header suit your build.
