be quiet! Silent Wings Pro 4 140mm PWM vs Noctua NF-A12x25 PWM: Comparison

be quiet! Silent Wings Pro 4 140mm PWM vs Noctua NF-A12x25 PWM: the airflow difference

The gap that matters here is airflow: be quiet! Silent Wings Pro 4 140mm PWM 97.4 CFM against Noctua NF-A12x25 PWM 60.09 CFM, which puts be quiet! Silent Wings Pro 4 140mm PWM 38% ahead. be quiet! Silent Wings Pro 4 140mm PWM also leads on static pressure, 3.64 mmH2O on the be quiet! Silent Wings Pro 4 140mm PWM versus 2.34 mmH2O on the Noctua NF-A12x25 PWM. Add max speed to that, 2400 RPM on the be quiet! Silent Wings Pro 4 140mm PWM versus 2000 RPM on the Noctua NF-A12x25 PWM, and the pattern holds. Warranty runs the same way, 5 years on the be quiet! Silent Wings Pro 4 140mm PWM versus 6 years on the Noctua NF-A12x25 PWM, another win for Noctua NF-A12x25 PWM.

Who each one is for

Buy the be quiet! Silent Wings Pro 4 140mm PWM for 280mm and 420mm AIO radiators and Quiet high-pressure builds, though it is not the pick for RGB-focused builds and open mesh cases where pressure is wasted. The Noctua NF-A12x25 PWM is the one to take for premium builds where noise and longevity matter most. It is equally the pick for buyers wanting the single best-tested all-around 120mm fan for any position. Avoid it for tight budgets filling an entire case, the Arctic P12 PST 5-pack is better value.
