Fantastiche ventole.
Ennesima ventola Noctua a casa mia. Che dire usata con il cavo che diminuisce la velocità, collegata con il cavo ad Y per la pwm del radiatore noctua del processore. Due ventole, una epr il radiaotre processore a piena velocità ed una per estrazione aria. !0 e lode e rumore zero. Abbassamento temperature del case fantastiche e senza rumore. Ho solo noctua in casa su 4 workstation e fra radiatori ed estrazione di vario genere nelle varie configurazioni non posso che consigliarle.

Perfect as always
I used these for my 6800pro Ugreen NAS. They fit perfectly and the airflow is increased but the noise is much reduced allowing me to leave it set on default. As you would expect these fans came with loads of adapters etc and were well packed. they were sturdy and the rubber corners helped with my metal chassis. The performancce of Noctua is always great and to me the the little bit more thay cos is worth it.

zeer stille ventilatoren die goed koelen
Inderdaad zeer stille ventilatoren, minstens zo goed als de eveneens kwalitatief goede E.M. Pabst fans van Duitse makelij. Voldoende luchtverplaatsing om je pc van binnen mee te koelen als je een paar in de pc kast zet. In de verpakking zaten nota bene nog extra aansluitkabels met ingebouwde potmeters om de snelheid van de fan mee te kunnen reguleren.

Silent, Efficient, and Perfect for NAS (or other small) Enclosures
I bought a few Noctua NF‑A9 PWM fans to replace the standard units in my NAS enclosure, and the improvements are noticeable from the moment they start spinning. The stock fans were noticeably loud, especially in a quiet room, but these Noctuas immediately brought the noise level down to something barely audible. For a device that runs 24/7 in a living space, that alone makes them worth it. Cooling performance is actually better than with the original fans. Temperatures dropped a few degrees under load, and the PWM control keeps everything smooth and stable without sudden ramp‑ups. Installation was straightforward, and the build quality is exactly what you expect from Noctua: solid, reliable, and engineered with care. If you want to keep your NAS (or any small enclosure) as quiet as possible without sacrificing cooling, this is an excellent upgrade. Highly recommended.
