ARCTIC P14 Pro Reverse 140mm PWM (ACFAN00329A)

The ARCTIC P14 Pro Reverse is a 140 mm PWM case fan with a reverse‑airflow design (intake from the back). It offers high static pressure (5.1 mm H₂O) and up to 98 CFM airflow, with a wide speed range of 400–2650 RPM — ideal for radiators, dense filters and setups where conventional fan orientation would hurt aesthetics.

Equipped with a Fluid Dynamic Bearing (FDB) for long life and low vibration, the P14 Pro Reverse supports PST (daisy‑chain PWM) and includes a 4‑pin PWM connector plus an additional 4‑pin socket for chained control.

Review — ARCTIC P14 Pro Reverse

The P14 Pro Reverse delivers strong static pressure and substantial airflow for a 140 mm fan. It performs well on radiators and through restrictive front panels; the reverse blade design preserves a clean intake look while maintaining performance. Noise at full speed is noticeable, so tuning is recommended for silent builds. Overall, excellent value for radiator or intake applications.

• Pros: high static pressure, reliable FDB bearing, PST daisy‑chain support.
• Cons: louder at maximum RPM; tune when noise matters.
