We have tested the Noctua NF-SFMA1 on the NZXT Kraken X62. NZXT has provided AER P 140mm fans with this cooler. The rated speed of the NZXT AER P 140 is 500 ~ 1800 +/- 300 RPM. Noise level rating is 21 – 38 dBA. Fan operates on 12V DC and draws 0.35A with an input power of 4.20W. These fans are PWM design with 4-pin PWM power connector. For comparison, we have tested the fans for which these brackets are designed in particular aka NF-A12x25. We have tested the PWM version of these fans. Their rated speed is 2000 +/- 10% RPM with sound level 22.6 dBA. Static pressure rating is 2.34 mmH2O. [...] The idle temps using the NZXT AER P were 1.99°C whereas the idle temps were 1.83°C with the Noctua NF-A12x25 PWM. This is a marginal difference but keep in mind these are 120mm Noctua fans vs NZXT 140mm fans and noise level difference is huge between both fans. Real comparison will come from the under load temps. Under load, the NZXT Kraken X62 was doing 38.83°C. With Noctua NF-A12x25 fans, the Kraken X62 was doing 38.5°C. Again we note a marginal difference but this is a significant boost in the performance from the 120mm fans using the 140mm bracket. Please, note that there is a 1 ~ 1.5m,m gap between the 120mm fans and the radiator when using this bracket. Against all odds, the fans have delivered a powerful punch.

"Against all odds the might and prime of the Noctua NF-A12x25 PWM outclass the competition in the noise-to-performance ratio. This goes to show that Noctua has brought out an accessory that would be a lethal cooling solution when coupled with their new generation NF-A12x25 (PWM/FLX) fans" (Nauman Siddique, EnosTech.com)
