Arctic P12 Pro PST CO (ACFAN00312A)

The Arctic P12 Pro PST CO is a 120 mm fan from the Pro series in Continuous Operation version, designed for extended 24/7 operation and ideal for servers, NAS systems, workstations, continuously loaded systems, and cases with high bearing durability requirements. The fan features a standard 120 × 120 × 25 mm format but operates at significantly higher speeds than typical consumer-grade models, with a range of 600–3000 rpm while supporting complete shutdown below 5% PWM. Maximum airflow reaches 77 CFM or 131 m³/h, and static pressure reaches 6.9 mm H₂O, making the Arctic P12 Pro PST CO particularly suitable for liquid cooler radiators, CPU coolers, dense dust filters, and metal meshes with high resistance. The key design feature is a dual ball bearing with an extended rotor shaft, which increases durability at high speeds and makes the model better suited for continuous operation. Additionally, PST technology enables synchronized PWM control of multiple fans through an integrated hub. Technical specifications include a 400 mm cable plus 80 mm daisy-chain connector, 12 V supply voltage, 3.3 V startup voltage, and 0.33 A current draw. The Arctic P12 Pro PST CO is a solution designed not for aesthetic builds but for systems where durability, pressure, and stable performance under high loads are the priorities.
