The ARCTIC P9 PWM PST CO is a 92 mm case fan for PC builders who need controlled airflow in a compact space. Its continuous-operation design also suits systems that run for long periods, such as workstations and always-on PCs.

PWM control adjusts the fan speed to match cooling demand, with a 0 rpm mode below 5% PWM for silent operation at low load. The pressure-optimised design helps maintain airflow where there is resistance, making the fan suitable for case ventilation as well as heatsinks and radiators. Its dual ball bearing is designed for continuous operation, while PST lets you connect another compatible fan to the supplied fan socket and share the control signal.

Key features

• PWM speed control lets a compatible motherboard adjust cooling to system demand.
• 0 rpm mode below 5% PWM allows the fan to stop when little cooling is needed.
• Pressure-optimised airflow is suited to restrictive areas such as heatsinks and radiators.
• PST connection passes the PWM signal through to another fan.
• Dual ball bearing supports continuous operation.
• Fan speed ranges from 200 to 3000 rpm under PWM control.
• Measures 92 x 92 x 25 mm for compatible fan mounts.

Compatibility

Connect the fan to a compatible 4-pin PWM fan header. Its 4-pin socket can connect another fan for shared control; check your motherboard manual for the header's current limit when connecting multiple fans. A 3-pin socket can accept the plug, but PWM speed control will not be available. Good to know: confirm your case, heatsink or radiator supports a 92 mm fan and has suitable mounting points before buying.
