The ARCTIC P14 Pro PST (White) is a 140 mm case fan for PC builders who need to cool a case, radiator or heatsink, including systems where air has to pass through a mesh filter or other restriction.

Its PWM control adjusts the fan speed from 400 to 2500 rpm, with a zero rpm mode below 5% PWM. The fan is designed for high air resistance, combining airflow of 110 cfm with static pressure of 5.2 mmH₂O. Its fluid dynamic bearing and revised blade design support smooth operation, while the PST connector lets you synchronise multiple fans in series from one motherboard fan header.

Key features

• 140 mm fan for case, radiator and heatsink cooling.
• PWM speed control from 400 to 2500 rpm.
• Zero rpm mode below 5% PWM.
• High static pressure helps move air through restrictive surfaces.
• Fluid dynamic bearing with an extended shaft to reduce vibration.
• PST socket allows additional fans to be synchronised from one header.
• Measures 140 x 140 x 27 mm and weighs 242 g.
• Rated airflow is 110 cfm and noise is 25 dB(A).

Compatibility

Connect the 4-pin plug to a compatible motherboard fan header for PWM control. The additional 4-pin socket supports daisy-chaining further fans; check that the header can supply enough power for the number connected. The fan is white and has no lighting. Good to know: Check your case or radiator has room for a 140 mm fan and 27 mm thickness, and confirm the fan header supports PWM.

Specifications

For a white build that needs controlled airflow through a radiator, mesh panel or heatsink, the P14 Pro PST combines high pressure performance with practical fan synchronisation in a single-fan package.
