ARCTIC P12 Pro PST

Controlled airflow for WindSim builds that need pressure, response and clean wiring.

ARCTIC P12 Pro PST is a 120 mm PWM fan with a built-in PST cable splitter. For a sim racing WindSim setup, that matters because the fan is not just moving air inside a PC case – it is being asked to react smoothly to control signals, push air through a duct or shroud and stay reliable during long sessions.

For WindSim use

A fan that makes sense when airflow is part of the driving feedback.

In a WindSim build, airflow needs to rise and fall with the control signal instead of feeling like a simple on/off blast. The P12 Pro PST gives you PWM speed control from 600 to 3000 rpm, with 0 rpm behavior below 5 percent PWM, so it can sit quietly at rest and ramp when the setup calls for air.

Pressure and airflow

Not every fan behaves well once you put it behind a shroud.

WindSim airflow is usually guided through a duct, grille, printed housing or cockpit mount. That is why static pressure matters. ARCTIC rates the P12 Pro PST at 77 CFM airflow and 6.9 mmH2O static pressure, giving it the headroom to push air through a more focused path instead of only working in open air.

77 CFM airflow

Enough airflow headroom for a serious sim racing wind effect.

6.9 mmH2O pressure

Useful when air is pushed through a duct, shroud or focused outlet.

PWM response

Fan speed can follow the controller signal instead of staying fixed.

4-pin connector

Standard 4-pin fan plug plus 4-pin socket for PST daisy chaining.

PST cable splitter

Cleaner cable routing when you run more than one fan.

PST is ARCTIC’s PWM-based synchronized fan control. The extra 4-pin socket lets multiple fans be connected in series from one PWM signal, which is useful when you want matching left and right WindSim behavior and a cleaner cable route around the cockpit. Power and current limits still need to match the controller you use.

FDB and balancing

Smoother operation matters when the fans sit near your face.

ARCTIC uses a Fluid Dynamic Bearing with an optimized bearing-shaft design, plus an automated balancing process. The point is simple: less vibration, smoother performance and a fan that feels more appropriate for long cockpit sessions than a cheap high-rpm fan buzzing on the rig.

More power, less noise

Strong airflow does not need to feel like a small turbine in the room.

ARCTIC positions the P12 Pro series around more performance at low speeds, with higher airflow and static pressure at just 25 dB(A). For sim racing this is useful because you want cooling and immersion, but you still need to hear the car, spotter, tyres and your own concentration.

WindSim Control Box ready

The fan is the airflow side – the control box is what makes it react.

Pair the P12 Pro PST with the OCRacing WindSim Control Box when you want game-telemetry-based fan control through SimHub. The fan itself is a 12 V 4-pin PWM fan; the control box handles the actual signal and power management needed for a proper WindSim setup.

What is in the box

One ARCTIC P12 Pro PST fan, ready for your WindSim build.

This product page is for the single fan variant of the ARCTIC P12 Pro PST. It is the correct choice when you need a replacement fan, want to build a custom left/right WindSim setup or want to keep the same fan model across both sides of the cockpit.
