be quiet! Silent Wings Pro 4 140mm PWM vs Noctua NF-A14 PWM: Comparison
be quiet! Silent Wings Pro 4 140mm PWM vs Noctua NF-A14 PWM static pressure compared
Static pressure is where these two genuinely part company, be quiet! Silent Wings Pro 4 140mm PWM 3.64 mmH2O against Noctua NF-A14 PWM 2.08 mmH2O, a 43% lead for be quiet! Silent Wings Pro 4 140mm PWM. be quiet! Silent Wings Pro 4 140mm PWM also leads on airflow, 97.4 CFM on the be quiet! Silent Wings Pro 4 140mm PWM versus 82.52 CFM on the Noctua NF-A14 PWM. Add max speed to that, 2400 RPM on the be quiet! Silent Wings Pro 4 140mm PWM versus 1500 RPM on the Noctua NF-A14 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-A14 PWM, another win for Noctua NF-A14 PWM.
Which should you buy, be quiet! Silent Wings Pro 4 140mm PWM or Noctua NF-A14 PWM?
The be quiet! Silent Wings Pro 4 140mm PWM is the one to take for 280mm and 420mm AIO radiators and Quiet high-pressure builds, though it is not built for RGB-focused builds and open mesh cases where pressure is wasted. Buy the Noctua NF-A14 PWM for Silent-focused builds and case intake/exhaust in mid or full towers, though it is the wrong buy for RGB-themed builds and budget multi-fan upgrades.
What be quiet! Silent Wings Pro 4 140mm PWM and Noctua NF-A14 PWM have in common
Where they agree, they agree completely, fan size, bearing type, connector type, lighting connector and fan thickness included, so the decision does not turn on any of those. They match on 4 further specifications as well.
