The ARCTIC P12 Pro PST (White) is a 120 mm case fan for PC builders who need to improve airflow through a radiator, mesh filter or perforated case panel. Its PWM control also suits systems where fan speed needs to respond to cooling demand.

High static pressure helps the fan move air through restrictive spaces. The revised blade design balances airflow with smooth operation, while the fluid dynamic bearing and extended shaft are designed to reduce noise and vibration. PWM Sharing Technology (PST) adds a second connector, so compatible fans can be synchronised from one motherboard header.

Key features

• 600–3000 rpm PWM speed range, with 0 rpm operation below 5% PWM
• Up to 77 cfm airflow and 6.9 mmH₂O static pressure
• Designed for radiators, mesh filters and perforated panels
• Fluid dynamic bearing and extended shaft help reduce noise and vibration
• Revised fan blades balance performance and smooth operation
• PST connector supports synchronised control of multiple fans from one header
• Automated balancing supports precise and smooth operation
• Six-year manufacturer warranty

Compatibility

This is a 120 mm case fan with a 4-pin fan plug and a 4-pin socket for daisy chaining. Check that your case or radiator has a compatible 120 mm mounting position and that your motherboard or fan controller provides a suitable 4-pin PWM header. Good to know: PST lets compatible fans share one PWM control signal, but each fan still needs suitable power from its connection.
