Noctua - Bild

Product discontinued.

The NF-B9's highly-optimised blade design achieves an exceptional level of airflow and static pressure that most other fans can only reach at much higher speeds. Bevelled blade tips, Vortex-Control Notches as well as Noctua's SCD drive system and premium-grade SSO-Bearing ensure outstanding quietness and long-term stability.

Test verdict: "Utilizzando la pasta termica della Noctua, le temperature sono diminuite di ben 13 gradi sotto un pesante stress, e per un PC non è certo poco. Quindi consigliamo sempre l’acquisto di una pasta termica professionale. Una di queste è la Noctua NT-H1,che associa efficienza, professionalità ad un prezzo di soli 7.90 €."

Test verdict: "If you need a low profile cooler for your server, mITX or HTPC, this will do you just fine. In fact, it will do you more than just fine, it does what a good product does well, high performance without the fuss." (Jim McGhee, Hardwareslave.com)

Test verdict: "With a 6 year warranty and MTBF rating over 150,000, the NH-U12S and NH-U14S are more affordable versions of the NH-D15 and uphold Noctua’s pedigree as the best supplier of air cooling solutions." (John Williamson, TruePCGaming.com)

26.05.2015 - Tweak.dk NF-A9 PWM
Test verdict: "Endnu en gang har Noctua leveret varen. De har modificeret og moderniseret en allerede god blæser til at blive om muligt endnu bedre. Denne blæser er blevet forbedret på flere områder, både når det gælder ydelse kontra støjforholdet, nyt og forbedret kugleleje og tilbehør. Alt i alt en rigtig god blæser, som flytter en masse luft uden at larme som en flyvemaskine." (Kim Monberg, Tweak.dk)
