ARCTIC COOLING ACFAN00135A P12 Value Pack 5×120mm 1800 RPM 56.3 CFM 0.3 Sone case fan

Five-pack pressure fans

The ARCTIC COOLING P12 Value Pack contains five 120 mm case fans built for static-pressure tasks such as radiators, heatsinks and partially obstructed vents. Each unit spins at 1800 RPM and delivers 56.3 CFM while the fluid-dynamic bearing keeps noise to 0.3 Sone. The 3-pin connectors draw little power and suit standard motherboard headers. Builders wanting a matched set for push-pull or multi-radiator loops get a consistent batch in one box.

Simple screw mounting

Installation uses the 20 supplied screws that thread directly into standard 120 mm fan mounts; no separate controller or proprietary brackets are included. The 25 mm thickness fits typical case and radiator clearance, but builders should verify their own chassis limits before fitting. A common issue is cable reach when fans are placed far from the header, so plan routing or have extensions ready. The 3-pin plugs lack PWM control, so speed is managed by voltage rather than a four-wire signal.

Steady output under load

During sustained operation the fluid-dynamic bearing maintains consistent RPM and airflow without the wear-related slowdown seen in sleeve designs. The pressure-optimised blades keep air moving through dense fin stacks even when system temperatures rise over long sessions. Noise stays at the rated 0.3 Sone because the motor does not need to ramp beyond 1800 RPM to overcome restriction. This makes the pack reliable for extended rendering, gaming or server workloads where continuous cooling matters.
