Noctua NF-A20 5V, Hoogwaardige Stille Ventilator met USB Adapterkabel, 3-Pins, 5V-uitvoering (200x30mm, Bruin)

Un must ! Silence impressionnant et efficacité redoutable pour refroidir mon ampli HC dans un meuble . Bouillant avant , avec le Noctua il est maintenant à température ambiante . Top ! De plus se branche sur l’usb de l’ampli( en 5v) . A noter pour un meilleur résultat, je l’ai mis sous l’ampli en extractation . Choisi en 20cm avec vitesse modérée mais la gamme compte beaucoup de modèles et des tensions variables . Top produit !👍

Fan aangekocht om de kast waar de computer en Synology NAS instaan te koelen, voordeel is dat de fan superstil is en aangesloten via USB, dus als de storage aan gaat begint de fan te draaien. Kast blijft lekker koel en alle apparaten draaien zo optimaal. Topproduct die noctua fans.

Nach einigen hin und her als Tischventilator gekauft, vor allem wegen der geringen Geräuschentwicklung. Ich muss sagen er tut was er soll. Sicherlich hat er nicht die power wie ein regulärer Ventilator (und halt in dieser USB Variante auch nur an oder aus) aber ich finde das Lüftchen perfekt so wie es ist, selbst an heißen Tagen.Für bessere Stabilität werde ich noch einen Fuss basteln oder eventuell auch die vorhandenen Schraubvorrichtungen nutzen.Pro:+ Leise+ Recht günstig+ Plug & Play+ Sicher verpackt und top Zubehör~ steht OK, braucht aber als Tischventilator noch einen kleinen Fuss den man sich sicherlich auch aus einem Karton bauen kann

Used as a make-shift personal fan during the summer, and it works.. well enough.As someone who owns other Noctua fans, this one has a slight buzzing sound - Im not sure if its the size of the fan itself, or just my fan, and this only happens at 800 (max) RPM, at lower speeds its virtually silent.The other thing is that it only maxes out at 800 RPM, it would be nicer if it could go even higher considering its a 200mm fan it should be able to handle it even if its only a 5V fan. Because of this its more of a "breeze" of wind rather than a storm. Also, Im assuming due to the fan design its more suited for static pressure rather than just airflow, and the wind it pushes seems to confirm this - as it spreads out through the sides almost cone-shaped rather than straight forward.All in all - as a temporary personal fan its fine, I wish that buzzing would go away, its not annoying enough for a replacement, but certainly noticable and something you dont want too close to you. I wish that it would go higher than 800 RPM, and that there was an air-flow optimized version rather than only a static-pressure optimized one.

Non posso che consigliare questo prodottoLa uso per raffreddare la parte sotto di un macbook pro che nei mesi estivi tende a riscaldarsi parecchio, adesso posto in verticale con la ventola a circa 1-2 cm che spara aria continuamente le temperature sono tornate normali, quindi meno stress per la batteria e minore riduzione del clock con conseguente mantenimento di buone prestazioni anche sotto stress (un paio di macchine virtuali e ambiente di sviluppo/testing a pieno regime) con temperature fino a 28-32 gradi in ambienteLa cosa sorprendente è quanto sia silenziosa questa ventola, anche in piena notte con silenzio totale risulta praticamente inudibile, ci si potrebbe dormire a meno di 50cm di distanza senza alcun disturbo
