140 mm Case Fan Pack arctic cooling ARCTIC P14 Pro PST — 5-pack, PWM, 400–2500 RPM, 186 m³/h, 5.2 mmH₂O, FDB, black
The ARCTIC P14 Pro PST 140 mm five-pack contains PWM-controlled case fans designed for efficient air movement in desktop PC enclosures and cooling systems. Each fan operates between 400 and 2500 RPM, provides up to 186 m³/h of airflow and 5.2 mmH₂O of static pressure, and is built with a Fluid Dynamic Bearing (FDB) to reduce operational noise and extend service life. The package includes a PWM splitter cable allowing synchronized speed control from a single motherboard header.
These 140 mm fans combine a wide speed range and high static pressure, making them suitable for both airflow-focused and resistance-heavy environments such as radiators or densely packed cases. Fluid Dynamic Bearing technology reduces friction and vibration for quieter operation and improved longevity compared with sleeve bearings. The included PWM splitter enables consistent, synchronized fan curves across all five fans, simplifying system tuning and ensuring coordinated cooling response.
Install the fans in the desired positions inside the PC case using the supplied mounting screws or vibration-damping mounts if available. Connect the 4-pin PWM connectors to the motherboard fan header; use the included splitter cable to connect multiple fans to a single header for synchronized control. Configure fan curves in the system BIOS or fan control software to match thermal profiles—set a low idle curve for quiet operation and increase speed thresholds for higher CPU/GPU loads or radiator cooling. Ensure correct airflow direction by aligning fan blades and frames as indicated by the directional arrows on the fan housing.
For radiator use, consider installing fans in a push or push-pull arrangement to maximize static pressure efficiency. In high-dust environments, pair the fans with removable dust filters and perform periodic cleaning to maintain airflow and cooling performance. When using the PWM splitter, verify the motherboard header’s current capability to ensure safe combined power draw and stable PWM signaling.
