The ARCTIC P12 Pro A-RGB LN is a 120 mm case fan for PC builders who want to improve chassis airflow while adding addressable lighting. Its balanced speed range suits quiet home or office systems as well as gaming PCs where cooling performance needs to respond to system temperature.

PWM control lets the fan adjust from 450 to 2000 rpm, and it can stop below 5% PWM for low-demand periods. The fluid dynamic bearing and revised fan blade design are intended to support smooth, quieter operation. The fan combines airflow of 49 cfm with static pressure of 3.5 mmH₂O, giving it flexibility for case ventilation and cooling through airflow-restrictive areas. Twelve A-RGB Gen2 LEDs provide customisable lighting, while the included splitter and daisy-chain connections help simplify wiring.

Key features

• PWM speed control across a 450–2000 rpm range
• Fan stop below 5% PWM for periods when active cooling is not needed
• Fluid dynamic bearing supports smooth, quieter running
• Revised fan blades balance airflow and operating noise
• Airflow rating of 49 cfm and static pressure of 3.5 mmH₂O
• Twelve A-RGB Gen2 LEDs for addressable lighting effects
• Fan and lighting connections support daisy chaining

Compatibility

Install the fan in a case with a compatible 120 mm mounting position. It uses a 4-pin PWM fan connection and a separate 3-pin A-RGB connection for 5 V lighting. The fan speed is adjusted using a PWM signal from the motherboard. Good to know: check that your motherboard or controller has compatible fan and 5 V A-RGB headers before buying; the two connections serve different functions.
