Noctua - Bild

The NF-A14 is a premium quality quiet 140mm fan with a square frame that complies with Noctua’s AAO (Advanced Acoustic Optimisation) standard. Its square shape and 140mm mounting holes (124.5mm spacing) make it ideal for use on watercooling radiators or as an upgrade for 140mm case fans. Featuring sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A14 further improves the renowned quiet cooling performance of the award-winning NF-P14. The ULN version provides super-slow 800/650rpm speed settings for ultra-low-noise applications and highly noise sensitive users who demand near-silent operation. Its superb running smoothness, reference-class SSO2 bearing and Noctua’s trusted premium quality make it an elite choice for the highest demands.

06.10.2015 - Always More Digital NH-C14S
Test verdict: "В итоге кулер Noctua NH-C14S получился весьма неплохим и заслуживает того, чтобы на него обратить внимание при покупке, пусть даже по современным реалиям его цена будет «кусаться», так как его рекомендованная стоимость равна 74,90 доллара." (Zastavnoy Mikhail Ivanovitch, Always More Digital)

06.10.2015 - NH-C14S
Test verdict: "Kto powinien zatem zainteresować się C14S? Na pewno posiadacze wydajnych procesorów po optymalnym OC, zamkniętych w wąskich obudowach, a także do wysokich radiatorów RAM-u. To główna zaleta konstrukcji, choć kusi także 6-letnia gwarancja." (Kamil Homziak,

Test verdict: "Ter algo como o NH-D15S é ter a supremacia máxima em dissipadores de computadores com troca de calor a ar." (Carlos Xandelly,
