The ARCTIC P12 Pro LN is a 120 mm PWM case fan for PC builders who want controlled airflow with a low-noise fan design. It suits desktop builds that need a standard 120 mm fan for case cooling.

PWM control lets the fan speed respond to the system’s cooling needs, with a stated range of 450–2000 rpm and a stop function below 5% PWM. Its Fluid Dynamic Bearing supports the fan’s design, while airflow of up to 49 cfm and static pressure of 3.5 mmH2O provide useful cooling performance for case ventilation.

Key features

• 120 mm fan format for compatible PC cases and mounts
• PWM control adjusts fan speed from 450 to 2000 rpm
• Stops below 5% PWM for periods when active fan rotation is not required
• Fluid Dynamic Bearing design
• Airflow rated at 83 m³/h or 49 cfm
• Static pressure rated at 3.5 mmH2O
• Four-pin fan plug for connection to a compatible motherboard or fan controller
• Six-year manufacturer warranty

Compatibility

Check that your case or cooler has a 120 mm mounting position and that your motherboard or fan controller has a compatible 4-pin fan header for PWM control. Good to know: the fan is supplied with four mounting screws; other cooling components and installation accessories are not specified as included.
