Corsair AF120 Slim vs Noctua NF-P14s redux-1500 PWM: Comparison
What is the difference between Corsair AF120 Slim and Noctua NF-P14s redux-1500 PWM?
The gap that matters here is airflow: Corsair AF120 Slim 56.3 CFM against Noctua NF-P14s redux-1500 PWM 78.69 CFM, which puts Noctua NF-P14s redux-1500 PWM 28% ahead. Static pressure is closer, 1.9 mmH2O on the Corsair AF120 Slim versus 1.91 mmH2O on the Noctua NF-P14s redux-1500 PWM. Noise level is closer, 25.6 dBA on the Corsair AF120 Slim versus 25.8 dBA on the Noctua NF-P14s redux-1500 PWM. Fan size is not the same on both, 120 mm on the Corsair AF120 Slim versus 140 mm on the Noctua NF-P14s redux-1500 PWM. Corsair AF120 Slim also leads on max speed, 2000 RPM on the Corsair AF120 Slim versus 1500 RPM on the Noctua NF-P14s redux-1500 PWM. There is a split on fan thickness as well, 15 mm on the Corsair AF120 Slim versus 25 mm on the Noctua NF-P14s redux-1500 PWM.
Which should you buy, Corsair AF120 Slim or Noctua NF-P14s redux-1500 PWM?
The Corsair AF120 Slim suits tight-clearance builds where a standard 25mm-thick fan won't physically fit. It is not the one for builds with no clearance constraints, a standard-thickness fan like the Noctua NF-A12x25 will generally outperform this one. Buy the Noctua NF-P14s redux-1500 PWM for budget-conscious builds that still want Noctua reliability and front intake positions behind a dust filter, though it is not the pick for builders who want the NF-A14's beige/brown aesthetic and maximum airflow per fan. Our rating of the Corsair AF120 Slim (7/10): A clearance-solving slim 120mm fan that keeps most of the airflow a standard-depth fan would give you. Our rating of the Noctua NF-P14s redux-1500 PWM (7/10): solid mid-range 140mm option that trades Noctua's premium finish for a friendlier price.
Where the two are identical
The common ground is wider than the gap: bearing type, lighting, pwm control and rgb lighting are identical here.
