ARCTIC P12 Pro PST — 120mm High-Pressure PWM Fan
600–3000 RPM77 CFM6.9 mmH₂OPWM PST
The ARCTIC P12 Pro PST ACFAN00306A is a 120mm pressure-optimised PWM fan designed for high airflow resistance applications such as radiators, heatsinks and restrictive case ventilation. It delivers up to 77 CFM airflow and 6.9 mmH₂O static pressure, with a controllable speed range of 600 to 3000 RPM and ARCTIC's PST daisy-chain connection for synchronised fan control.
Compatibility — check before buying:
This is a 120 × 120 × 25 mm, 12V PWM fan. Confirm that your case, radiator or heatsink provides a 120mm mounting position and that the motherboard or fan controller has a compatible 4-pin PWM header. The PST socket allows additional compatible PWM fans to share the same control signal.
Best For
✓ 120mm radiator cooling
✓ Heatsinks and restrictive ventilation
✓ High-performance PWM case cooling
✓ Multi-fan systems using PST daisy-chaining
Key Features
High static pressure
The P12 Pro PST reaches up to 6.9 mmH₂O static pressure, making it particularly suitable where airflow must pass through dense radiator fins, heatsinks, filters or restrictive vents.
600–3000 RPM PWM control
The wide PWM-controlled speed range allows the fan to adapt to changing cooling requirements. ARCTIC also specifies 0 RPM operation below a 5% PWM signal when the controller provides the required control range.
PWM Sharing Technology
A 4-pin fan plug and additional 4-pin PST socket let compatible fans share one PWM control signal. The supplied cable arrangement includes a 400mm main cable plus an 80mm daisy-chain lead.
Fluid Dynamic Bearing
ARCTIC equips the P12 Pro PST with a Fluid Dynamic Bearing and backs the fan with a six-year manufacturer warranty.

Frequently Asked Questions
Singular Expert Insight
The P12 Pro PST is substantially more pressure-focused than a typical general-purpose 120mm case fan. Its 6.9 mmH₂O static pressure and 3000 RPM maximum make it a strong fit for dense radiators, heatsinks and restrictive airflow paths, while PWM control lets the system reduce speed when that performance is not required. PST is also useful in multi-fan radiator installations because compatible fans can share one motherboard PWM signal.
Buyer’s Guide
Buy it if
You need a high-pressure 120mm PWM fan for a radiator, heatsink or restrictive case location and want PST connectivity for synchronised multi-fan control.
Check first
Confirm a 120mm mounting position, 25mm depth clearance and a suitable 4-pin PWM header. Remember that the fan can draw up to 0.33 A at 12V.
Choose another model if
You require a different fan size, RGB lighting, a white fan or a multi-pack. ARCTIC uses separate part numbers for those P12 Pro variants.
