The ARCTIC P12 Pro PST White is a high-performance 120-millimeter PWM fan designed for efficient cooling of computer systems, even in situations where the air must overcome higher resistance. Due to its high static pressure, it is particularly well-suited for water-cooling radiators, perforated panels, and mesh filters, but it can also be used as a high-performance fan for airflow through the case. The white version is suitable for light-colored or color-coordinated PC setups.

The fan operates in the 600–3,000 RPM range and delivers up to 131 m³/h of airflow and as much as 6.9 mmH₂O of static pressure. PWM control allows for precise speed adjustment based on system temperature, and the fan can stop completely under light load. ARCTIC uses a Fluid Dynamic Bearing (FDB) with an optimized shaft design, automated balancing, and a SOTA microcontroller, which reduces motor noise, compensates for load fluctuations, and ensures smooth operation.

A unique feature of this model is PST—PWM Sharing Technology—which allows for the daisy-chain connection of multiple fans and their synchronized control via a single PWM header on the motherboard. The fan comes with a 400-mm cable and an additional 80-mm daisy-chain cable, making it easy to install multiple fans neatly without the need for additional splitters.

Key advantages:

• 120-mm high-performance PWM fan
• speed: 600–3,000 RPM
• Airflow up to 131 m³/h
• Up to 6.9 mmH₂O of static pressure
• Optimized blade design for high performance with higher air resistance
• Fluid Dynamic Bearing (FDB) for smooth and quieter operation
• Automated balancing to reduce vibrations
• SOTA microcontroller for reducing motor noise and protecting electronics
• PST (PWM Sharing Technology) for synchronous control of multiple fans
• Option to stop the fan at less than 5% PWM
• 4-pin PWM connector + 4-pin socket for daisy-chain connection
• 400 mm cable + additional 80 mm for connection
• Dimensions: 120 × 120 × 25 mm
• Weight: 185 g
• White finish

From a commercial standpoint, the P12 Pro PST White is primarily intended for gaming and high-performance computer systems where cooling performance is more important than RGB lighting. Thanks to its 6.9 mmH₂O static pressure, it is particularly well-suited for use with AIO coolers and other systems with limited airflow, while the PST connection simplifies the installation of multiple fans in the same case. Compared to the A-RGB version, it offers the same performance without lighting, making it suitable for more understated or professional setups.
