Even at full pelt, the 1,500rpm version is extremely quiet, forgoing any buzz or clicks that often plague other 140mm models. This is particularly apparent on NF-A14x25 G2 PWM Sx2-PP, which is a push-pull set of two. Despite more or less being the same fans included in the regular kit, Noctua offsets the speed of each push-pull fan by 25rpm to prevent harmonic resonance. It’ll also stop completely if it registers a 0rpm signal, rather than being beholden to a minimum speed like most PWM fans.
Comparatively, sound profiles aren’t worlds apart from be quiet! Silent Wings 3, but Noctua NF-A14x25 G2 fares far better with temperatures. Pitting the two against each other on top of a Pure Loop 280 that’s cooling Intel Core i9-13900K, Noctua’s latest fans shave up to 5°C off while running Cinebench 2024 using a stable 153W.
