ARCTIC
A 140 mm PWM case fan optimised for static pressure on heatsinks and radiators, running at 200–1700 RPM with 72.8 CFM airflow and 0.3 Sone noise
The ARCTIC P14 PWM is a 140 mm case fan built for high static pressure. Its blade geometry and motor are tuned to push air through dense heatsinks and radiators where resistance is high. The 4-pin PWM connector lets the motherboard vary speed from 200 to 1700 RPM. It suits builders who need focused airflow in restricted paths.
Typical case fans move air freely but stall against a radiator or thick fin stack. This model replaces those when the cooling path adds resistance and temperatures climb. The jump is worth it when a CPU cooler or liquid radiator cannot breathe with regular fans. It is not for builds that only need high volume flow through open mesh.
At 1700 RPM the fan delivers 72.8 CFM (123.76 m³/h) at 0.3 Sone. A neodymium-iron-boron magnet ring lowers coil temperature by roughly 10 °C, which the maker says quadruples service life. The motor therefore runs cooler and keeps its speed steady during long sessions. Buyers who need silence at idle but headroom under load will notice the difference.

Yes, the fan uses a standard 140 mm square frame with corner screw holes that match typical case mounts.
Plug the 4-pin connector into a motherboard PWM header; the board then varies voltage on the fourth wire to regulate speed automatically.
Clean dust from blades every 6–12 months with compressed air; replace only if bearings become noisy or RPM drops below 200 at full PWM.
