The ARCTIC P12 Pro Reverse is a 120 mm case fan for PC builders who want to bring air into a system while showing the fan’s cleaner side through a window or mesh panel. Its reverse airflow direction can suit layouts where a conventional fan’s intake direction or visible side does not work for the build.

PWM control lets the fan adjust its speed to cooling demand, from 500 to 3000 rpm, and it stops below 5% PWM. The design combines a fluid dynamic bearing with airflow features intended to reduce turbulence and resistance. A 4-pin socket and an 80 mm daisy-chain cable also let you connect another compatible fan in sequence, helping simplify fan wiring.

Key features

• Reverse airflow design for rear-side air intake layouts.
• 120 mm frame with a 27 mm thickness.
• PWM speed control from 500 to 3000 rpm.
• Fan can stop below 5% PWM.
• Airflow reaches 73 cfm | 124 m³/h.
• Static pressure is rated at 4.5 mmH2O.
• Fluid dynamic bearing supports smooth operation.
• 4-pin socket and daisy-chain cable allow another compatible fan to connect in sequence.

Compatibility

Designed for a 120 mm fan mount and powered from a 12 V DC fan connection. PWM speed control requires a suitable 4-pin motherboard fan header; the 4-pin plug can connect to a 3-pin socket, but PWM control will not be available. Good to know: check your case clearance for the 27 mm thickness and plan the airflow direction before installation; four mounting screws are included.

Specifications

For a build that needs deliberate reverse airflow, PWM adjustment and cleaner fan cabling, the P12 Pro Reverse brings those features together in a single 120 mm fan.
