Description
ARCTIC P12 Pro Reverse A-RGB PWM 120mm Chassis Fan
ACFAN00322A
The ARCTIC P12 Pro Reverse A-RGB PWM Fan (ACFAN00322A) is a unique 120 mm reversed-airflow cooling fan that combines effective thermal performance with vibrant addressable RGB lighting. Unlike standard fans that push air in a conventional direction, this fan pulls air from the opposite side, offering flexibility in airflow routing for custom chassis builds or unconventional cooling setups.
With a wide PWM speed control range (500 – 3000 RPM), the fan adapts from quiet operation under light loads to strong airflow when cooling demand increases. The integrated Gen2 A-RGB lighting is compatible with major motherboard RGB sync software (e.g., ASUS Aura Sync, MSI Mystic Light, Gigabyte RGB Fusion), allowing you to customise and synchronise lighting effects with the rest of your system.
The fluid dynamic bearing (FDB) ensures smooth, quiet performance and extended longevity compared to cheaper bearings — making this fan suitable for both everyday systems and gaming rigs. Daisy-chain-capable PWM and ARGB connectors help keep cable routing tidy in multi-fan configurations if you add more later.
Why It’s a Great Choice
Reversed Airflow for Flexibility:
This fan’s reverse airflow design gives you more flexibility when planning intake/exhaust directions, especially in builds where traditional airflow paths are restricted or aesthetic choices matter.
Dynamic PWM Control:
With a wide 500 – 3000 RPM PWM range, this fan scales from quiet everyday operation to powerful cooling under higher thermal loads — balancing acoustics and performance.
Good Airflow & Pressure for Its Size:
With ~73 CFM airflow and ~4.5 mm H₂O static pressure, this fan can handle both free-flow case ventilation and airflow through filters or moderate resistance.
ARGB Lighting Integration:
The Gen2 A-RGB lighting lets you synchronise vibrant lighting effects with supported motherboard RGB ecosystems, enhancing visual appeal without extra controllers.
Quiet & Durable Operation:
Fluid dynamic bearing design means smoother operation and longer life compared to sleeve bearings, making the fan a solid choice for 24/7 systems.
Simplified Wiring:
Standard 4-pin PWM and 3-pin ARGB connectors (with daisy-chain capability) keep wiring neat and make fan speed and lighting control easy in multi-fan setups.
Long Warranty Confidence:
Backed by ARCTIC’s 6-year warranty, giving peace of mind for long-term reliability in performance and aesthetic builds.
