be quiet! Light Wings 140mm PWM high-speed vs Lian Li UNI FAN P28 static pressure compared
Start with static pressure, because it is the widest measured gap between them: be quiet! Light Wings 140mm PWM high-speed 2.3 mmH2O against Lian Li UNI FAN P28 4.79 mmH2O, 52% in favour of Lian Li UNI FAN P28. Airflow runs the same way, 71.7 CFM on the be quiet! Light Wings 140mm PWM high-speed versus 92 CFM on the Lian Li UNI FAN P28, another win for Lian Li UNI FAN P28. Add warranty to that, 3 years on the be quiet! Light Wings 140mm PWM high-speed versus 6 years on the Lian Li UNI FAN P28, and the pattern holds. Max speed runs the same way, 2200 RPM on the be quiet! Light Wings 140mm PWM high-speed versus 2600 RPM on the Lian Li UNI FAN P28, another win for Lian Li UNI FAN P28.
Who each one is for
The be quiet! Light Wings 140mm PWM high-speed is the one to take for ARGB case intake/exhaust wanting real airflow and 140mm front-panel installs, though it is not the pick for pure silence at max speed (use the standard, non-high-speed variant) and radiator duty needing high static pressure. It is equally the pick for builders loyal to be quiet!'s acoustic tuning who still want lighting. Buy the Lian Li UNI FAN P28 for thick, high-FPI custom-loop radiators and builders who want daisy-chain cabling with real performance, though it is not built for Quiet-first case airflow duty and budget builds.
