ARCTIC P14 Pro PST CO Fan - 140mm PWM

ARCTIC P14 Pro PST CO is a 140 mm PWM fan aimed at those who want serious airflow and pressure for a case or radiator without turning their machine into a vacuum cleaner. It operates in a wide range of 400–2500 RPM, giving you flexibility – from nearly silent idle to aggressive cooling under load. At maximum, the airflow reaches up to 110 CFM, and the static pressure is up to 5.2 mmH2O, which is important if it will pass through dense radiators or filters. There is no RGB, everything is clean in black, so it's a good choice if you prefer a functional rather than a "glowing" build.

What you get

With a size of 140 x 140 x 27 mm, the P14 Pro PST CO is thicker than standard 25 mm fans, which helps for more serious airflow and pressure in the same form factor. The 2 Ball Bearing bearings are designed to last long and operate stably at higher speeds and in heavier environments – a good option for 24/7 machines or warmer rooms. With PWM 4-pin control, you can set the RPM curve so that at low load the fan stays around 400 RPM and is almost inaudible, while during gaming or rendering it ramps up for maximum cooling. The noise level up to 25 dBA for such airflow is perfectly fine, especially if you control it through the motherboard or a separate controller. It operates on standard 12 V, so you connect it directly to the motherboard or fan hub and forget about it.

• 140 mm PWM fan – larger blade for more air at the same or lower speeds compared to 120 mm variants.
• 400–2500 RPM RPM range, allowing for both quiet mode and aggressive cooling when needed.
• Up to 110 CFM airflow, suitable for cases with limited airflow or dense filters.
• Static pressure 5.2 mmH2O, making it a sensible choice for radiators and dense mesh panels.
• 2 Ball Bearing bearing for longer life and reliable operation in vertical and horizontal mounting and long 24/7 operation.
• Noise level up to 25 dBA, so with the right fan curve it can keep the system quiet during everyday use.
• 72 months warranty, which is a serious term for a fan and shows a focus on durability.

Who it is suitable for

This fan is suitable if you are building a gaming or workstation machine that needs to be well-cooled, especially with an AIO radiator or a dense front mesh case. It is also suitable for 24/7 systems – a home server, NAS, mini workstation – where long bearing life and stable operation are important. If you are after a colorful RGB show, you won't find it here – this is a fan for people who want air and reliability above all.

The combination of high airflow, serious static pressure, 2 Ball Bearing bearing, and a long 72-month warranty makes the ARCTIC P14 Pro PST CO a very sensible choice for cooling a case or radiator when the goal is a practical and long-lasting build.
