Very quiet
Got 3 of these in my 1U server and it’s very quite, compared to my old fans.

Producto muy bueno, envío premium lento.
Noctua es símbolo de calidad aunque un poco caro son sus productos.Para Canarias no recomiendo los envíos premium ya que tardan lo mismo que los normales.

Running it inside Mikrotik CRS317-1G-16S+
Adding adding 10G copper transceivers, the stock fans were unbearably whiny because the copper transceivers run crazy hot. I swapped the stock fans to these and now all I get is peace and tranquility.

Super Leise und Leicht zu installieren
Ich habe diese Lüfter gekauft um den Geräuschpegel diverser Netzwerkgeräte in meinem Serverschrank zu reduzieren.Die Installation ist einfach und man hat so einiges an Zubehör dabei.Die Lüfter sind ausserordentlich Leise und fast nicht zu hören.Die Kühlleistung ist akzeptabel, aber natürlich nicht vergleichbar mit echten Server-Lüftern.Für wen aber ein paar Grad mehr in den Geräten im Gegenzug zu deutlich leiseren Lüftern akzeptabel ist, sind diese hier sehr zu empfehlen.

四隅のゴムは無いのと変わらないけど
高回転で静か、風量も十分あるチップセット冷却に使ってます。

Would recomend
These are great fans, small but surprisingly quiet, especially compared to the fans they replaced
