ARCTIC P14 Pro PST (ACFAN00314A, single fan)
A 140 mm PST fan with a 27 mm frame that needs a little more installation depth.
The P14 Pro PST suits a build with verified 140 mm positions and a plan for linked PWM control. Its 27 mm thickness deserves attention on radiators and in compact clearances. Choose it for the actual mount and control needs, not because a larger fan automatically guarantees lower noise than a particular 120 mm design.
Consider it when
- A compatible 140 mm intake or radiator position with sufficient depth.
- A coordinated fan group within the motherboard header’s electrical limit.
Look again when
- A 25 mm-deep space assumed adequate without measurement.
- A case that lists 140 mm fan support in a different position from the intended mount.
THE SPACE IT NEEDS
Match the frame and the available depth
- Nominal frame size
- 140mm
- Fan thickness
- 27mm
Nominal frame size is not mounting-hole spacing. Check screw locations, thickness, cable routing and any radiator or nearby components.
Check case-fan installation ↗Based on the manufacturer specification record, checked . Check the exact revision and installation instructions before buying.
The checks that can change your choice
Use the right screw length
A thicker frame changes the required mounting arrangement. With a radiator, use compatible screws and avoid driving an overly long screw into the radiator; with a case, verify secure mounting and blade clearance.
Check the whole PST chain
The stated range is 400–2500 RPM with a stop region below 5% PWM. Add all fan currents, check header capacity and confirm that the chosen curve starts the complete group reliably after a stop.
