140 mm Fan Arctic P14 PWM PST RGB 0dB — 1900 RPM, 68.9 CFM, FDB, 12 V

The Arctic P14 PWM PST RGB 0dB is a 140 mm semi-passive case and cooler fan designed for PC chassis and radiator installations where PWM control and integrated digital RGB lighting are required. The fan operates at up to 1900 RPM on a 12 V supply and provides a maximum airflow of 68.9 CFM (117.06 m³/h). It uses a Fluid Dynamic Bearing (FDB) to extend operational life while maintaining low noise output (0.3 sone). This model includes PST (PWM Sharing Technology) for synchronized speed control across compatible fans and features digital RGB which requires a compatible motherboard or controller for lighting effects.

Advantages

The Fluid Dynamic Bearing reduces wear and supports longer service life compared with standard sleeve bearings while keeping operational noise low. PWM control with PST compatibility enables precise automatic fan speed management tied to system temperatures, improving cooling efficiency and reducing unnecessary noise. The 140 mm frame balances high airflow and moderate static pressure for case and radiator use, and the integrated digital RGB provides customizable lighting without a separate dedicated RGB controller when connected to compatible systems.

Suitable for

• Case cooling in mid-tower and full-tower PC builds
• Radiator cooling for AIO liquid coolers that accept 140 mm fans
• Systems requiring PWM speed control and synchronized fan operation
• Builds with motherboard or controller support for digital RGB lighting

How to use

Install the Arctic P14 PWM PST RGB 0dB into a compatible 140 mm fan mounting location in your PC chassis or onto a radiator designed for 140 mm fans. Connect the main PWM power cable to a motherboard fan header that supports PWM control; for synchronized speed via PST, link additional compatible fans according to the manufacturer's instructions. Connect the digital RGB cable to a compatible RGB header or controller to enable lighting; refer to your motherboard or controller manual for pinout and software configuration. Ensure screws are fitted securely and that the fan airflow direction matches your intended intake or exhaust setup.

Usage recommendations

For optimal balance between cooling performance and noise, use motherboard fan curves or software to let PWM control adapt fan speed to system temperatures. When installing multiple fans, use PST chaining for unified control and confirm digital RGB compatibility with your motherboard or controller before purchase to avoid lighting configuration issues.
