NF-A20 FLX,NF-A20 PWM
At roughly 34.5dBA, +/- 0.5dBA, the Noctua fan pushes 424LPM, where Cooler Master does 334LPM. At 33dBA, we’re running 386LPM on Noctua, and 302LPM on Cooler Master. 31dBA has us at 316LPM and 275LPM, respectively. [...] The Noctua fan remains generally ahead, but has a wider acoustic performance lead at the low-end. If you recall, Cooler Master had a bit of an LPM lead at the same low-end, which would mesh with these noise findings.
"[T]he Noctua fan pushes a higher LPM than Cooler Master at the higher RPMs, and manages to do so while retaining competitive noise levels. The Noctua NF-A20 could be run at 90% and achieve similar airflow and acoustic performance to the Cooler Master fan at 100%, which is potentially beneficial to some noise-sensitive users;" (Stephen Burke, GamersNexus.net)
