Noctua NF-P14s redux-1200 vs Scythe Kaze Flex II 120 PWM: Comparison
What is the difference between Noctua NF-P14s redux-1200 and Scythe Kaze Flex II 120 PWM?
On static pressure the spread is 25%, Noctua NF-P14s redux-1200 1.29 mmH2O against Scythe Kaze Flex II 120 PWM 0.97 mmH2O, so Noctua NF-P14s redux-1200 takes it. Noctua NF-P14s redux-1200 also leads on airflow, 64.92 CFM on the Noctua NF-P14s redux-1200 versus 52.94 CFM on the Scythe Kaze Flex II 120 PWM. Fan thickness is not the same on both, 25 mm on the Noctua NF-P14s redux-1200 versus 26 mm on the Scythe Kaze Flex II 120 PWM. They differ on pwm control too, No on the Noctua NF-P14s redux-1200 versus Yes on the Scythe Kaze Flex II 120 PWM. There is a split on rated life as well, 150000 hours on the Noctua NF-P14s redux-1200 versus 120000 hours on the Scythe Kaze Flex II 120 PWM.
Which should you buy, Noctua NF-P14s redux-1200 or Scythe Kaze Flex II 120 PWM?
The Noctua NF-P14s redux-1200 is the one to take for budget 140mm case intake/exhaust and quiet HTPC builds, though it is not the pick for radiator or heatsink duty and max-airflow positive-pressure builds. The Scythe Kaze Flex II 120 PWM suits quiet mainstream case airflow and Non-RGB builds, though it is the wrong buy for high static pressure radiator duty and show-window RGB builds. Our rating of the Noctua NF-P14s redux-1200 (7/10): A sensible budget 140mm pick when you want Noctua's fit and finish without paying for the flagship A-series. Our rating of the Scythe Kaze Flex II 120 PWM (7/10): A dependable, quiet mainstream fan with nothing flashy about it, which is exactly the point.
