The ARCTIC P12 Pro PST LN is a 120 mm PWM case fan for PC builders who want controlled airflow with a speed range tuned for quieter operation. It suits a desktop build where a fan may need to move air through a case grille, mesh panel or radiator while keeping lower-speed running in mind.

Its fluid dynamic bearing and PWM control support adjustable fan speed from 450 to 2000 rpm, with the fan stopping below 5% PWM. The PST cable splitter lets you connect another compatible fan in a chain, helping simplify fan connections in a multi-fan setup. At its rated maximum, it delivers 49 cfm of airflow and 3.5 mmH₂O static pressure.

Key features

• 120 mm frame fits builds designed for this standard fan size.
• PWM control allows the motherboard to adjust fan speed to suit cooling needs.
• 0 rpm operation below 5% PWM can stop the fan at very low control signals.
• 450–2000 rpm speed range is designed around a balance of airflow and quiet operation.
• Fluid dynamic bearing supports smooth fan operation.
• 49 cfm airflow and 3.5 mmH₂O static pressure suit airflow through restrictive case panels or radiators.
• PST splitter cable provides a 4-pin fan plug and a 4-pin socket for linking another fan.

Compatibility

Check that your case, radiator or cooler has room for a 120 x 120 x 25 mm fan, and connect it to a suitable 4-pin PWM fan header. The PST socket can be used to link another fan, subject to the power capacity of the motherboard header. Good to know: a 3-pin socket can accept the 4-pin plug, but PWM speed control will not be available.

Specifications

For a compact case build or a radiator installation that needs a 120 mm fan with PWM adjustment and a linkable cable, the P12 Pro PST LN offers a considered mix of airflow capability and low-speed control.
