Noctua NF-F12 PWM vs Phanteks SK123-140 D-RGB: Comparison
Noctua NF-F12 PWM vs Phanteks SK123-140 D-RGB: the airflow difference
Airflow is where these two genuinely part company, Noctua NF-F12 PWM 54.97 CFM against Phanteks SK123-140 D-RGB 74.0 CFM, a 26% lead for Phanteks SK123-140 D-RGB. Add static pressure to that, 2.61 mmH2O on the Noctua NF-F12 PWM versus 1.9 mmH2O on the Phanteks SK123-140 D-RGB, and the pattern holds. Noise level is closer, 22.4 dBA on the Noctua NF-F12 PWM versus 29.7 dBA on the Phanteks SK123-140 D-RGB. They differ on fan size too, 120 mm on the Noctua NF-F12 PWM versus 140 mm on the Phanteks SK123-140 D-RGB. There is a split on lighting as well, None on the Noctua NF-F12 PWM versus D-RGB on the Phanteks SK123-140 D-RGB. They differ on positioning too, Premium on the Noctua NF-F12 PWM versus Mainstream on the Phanteks SK123-140 D-RGB.
Noctua NF-F12 PWM vs Phanteks SK123-140 D-RGB: which one fits your build
Buy the Noctua NF-F12 PWM for CPU tower cooler fans and thin 120mm AIO radiators, though it is not the pick for budget multi-fan case builds and RGB-focused builds. The Phanteks SK123-140 D-RGB suits 140mm case intake/exhaust and Phanteks case builds, though it is not built for radiator duty and silent builds. Our rating of the Noctua NF-F12 PWM (9/10): the benchmark focused-flow 120mm fan for CPU coolers, still worth the premium for the one or two fans that actually sit on a heatsink. Our rating of the Phanteks SK123-140 D-RGB (7/10): A well-rounded 140mm intake fan for Phanteks cases that want lighting without sacrificing airflow.
What Noctua NF-F12 PWM and Phanteks SK123-140 D-RGB have in common
The common ground is wider than the gap: bearing type, max speed and pwm control are identical here.
