ARCTIC P14 Pro Reverse PWM PST 140 mm fans, 3-pack, black
Delivery options to:
Choose countryThe ARCTIC P14 Pro Reverse PWM PST is a pack of 3 black 140 mm case fans designed to draw air in from the back. This reverse-airflow layout suits installations where conventional fans would compromise the desired appearance.
Airflow and speed control
High static pressure helps move air through radiators, perforated panels and mesh filters. PWM control adjusts speed from 400 to 2650 RPM, with the fans stopping at PWM signals below 5%.
- PST synchronisation: an additional 4-pin socket lets multiple fans be daisy-chained and controlled from a single header.
- FDB bearing: a fluid dynamic bearing and extended shaft help reduce vibration and operating noise.
- Motor control: the microcontroller reduces motor noise, compensates for load fluctuations and protects against inrush currents and reverse polarity.
Fit and connection
Each fan measures 140 × 140 × 30 mm, so the mounting space must accommodate its 30 mm thickness. The fans use 12 V DC power and have a 400 mm cable plus an 80 mm daisy-chain cable. Revised blades, minimal gaps and precise balancing support smooth operation and efficient airflow.
