ARCTIC P12 Pro Reverse PWM 120mm 3 Pack Chassis Fans
ACFAN00332A
The ARCTIC P12 Pro Reverse 3-Pack (ACFAN00332A) bundles three specialised 120 mm PWM cooling fans with a reversed airflow design, meaning air is pulled in from the opposite side compared to standard fans — useful for specific build orientations where traditional airflow directions are restricted or aesthetically undesirable.
Each fan supports a wide 500 – 3000 RPM PWM speed range, letting them run quietly under lighter loads and ramp up when extra airflow is required. With strong airflow and solid static pressure, these fans are effective at moving air even through filters, mesh panels, or constrained chassis spaces.
Built with fluid dynamic bearings (FDB), these fans provide smooth and quiet performance with improved longevity compared to sleeve bearings. The daisy-chain-capable PWM connectors make it easy to synchronise all three fans from a single motherboard fan header — simplifying wiring and ensuring uniform cooling performance.
Why It’s a Great Choice
Reversed Airflow for Unique Layouts:
This fan’s reverse airflow design lets you pull air in the opposite direction of most standard fans — ideal for builds with non-traditional airflow patterns or spatial restrictions.
Adaptive PWM Control:
The 500 – 3000 RPM PWM range lets the fans run quietly under low usage and deliver powerful airflow when the system heats up — giving a balance of acoustics and cooling performance.
Solid Airflow & Pressure:
With ~73 CFM airflow and ~4.5 mm H₂O static pressure, these fans move air effectively through restrictive environments like mesh filters or tight chassis spaces — making them suitable for intake/exhaust roles even in compact builds.
Quiet, Durable Bearings:
Fluid Dynamic Bearings reduce operational noise and extend the fan’s service life compared to cheaper bearing types, making these fans reliable even under frequent use.
Simplified Multi-Fan Control:
With daisy-chain-ready PWM connectors, all three fans can be controlled from one motherboard header — making cable management cleaner and ensuring synchronized fan speed changes.
Versatile Cooling Roles:
Great as intake/exhaust fans in specialised airflow builds, or for cooling tight spaces where standard airflow direction isn’t optimal — such as behind radiators or unconventional chassis layouts.
Long Warranty Confidence:
Backed by ARCTIC’s 6-year manufacturer warranty, giving peace of mind for long-term operation and durability.
