The ARCTIC P14 Pro PST (ACFAN00314A) is a high‑performance 140 mm case fan engineered for demanding airflow and pressure‑intensive cooling scenarios. Designed as the next evolution of ARCTIC’s proven P‑series, the P14 Pro targets users who require maximum cooling efficiency for radiators, dense mesh panels, and restricted airflow environments.
At its core, the fan operates across a wide PWM‑controlled speed range from 400 to 2500 RPM, allowing it to function quietly during idle operation and aggressively ramp up when system thermal demands increase. Thanks to its advanced seven‑blade aerodynamic design and minimized blade‑to‑frame gap, the P14 Pro delivers an impressive 110 CFM of airflow and an exceptional 5.2 mmH₂O static pressure, making it highly effective even against significant airflow resistance.
Noise control is handled intelligently through PWM regulation, including a 0 RPM mode below 5 percent PWM, which allows the fan to stop completely under low thermal load. This ensures near‑silent system operation during light workloads without sacrificing instant cooling response when needed. The refined motor design is supported by a fluid dynamic bearing, chosen for smooth rotation, reduced vibration, and long‑term durability under continuous use.
A key feature of the P14 Pro PST is ARCTIC’s PST (PWM Sharing Technology). Each fan is equipped with both a PWM input and output connector, enabling multiple fans to be daisy‑chained and synchronized from a single motherboard header. This simplifies cable management and ensures consistent speed control across multi‑fan configurations.
Finished in a clean, understated black design, the ARCTIC P14 Pro PST integrates seamlessly into both performance‑focused and minimalist PC builds. With its combination of extreme static pressure, broad PWM range, and intelligent daisy‑chain control, the P14 Pro PST stands as an excellent choice for builders who want uncompromising cooling performance, precise control, and long‑term reliability in a 140 mm format.
