4.0 out of 5 stars Leiser Lüfter, kleine Unwucht
Reviewed in Germany on 26 June 2019
Dies hier ist mein 4.ter Noctua Lüfter, ich habe bereits zwei 40mm sowie einen Ultra dünnen 92mm Lüfter bestellt und bin Höchst zufrieden. Ich habe hier die 5V variante mit PWM bestellt um einen kleinen Tischventilator zu bauen, der mich nicht durch Geräusche nervt und das ist mit diesem Lüfter auch gelungen.

Ich habe diesen Lüfter mit ca. 18db mit einem Lüfter verglichen mit 140mm und 30db. Der Noctua ist klar leiser, die durchflussmenge an Luft ist gefühlt die selbe, laut Datenblatt aber etwas mehr beim Noctua.
PWM habe ich gewählt um eventuell später mit einem zusätzlichen Regler der ebenfalls von Noctua angeboten wird (ich glaube NF-FC oder so ähnlich) noch Manual die Drehzahl anzupassen.

Die 5V Variante habe ich genommen, da man es direkt über USB betreiben kann, bei einer sensationell geringen Stromaufnahme von nur 0,85w. habe den Noctua damit 10 Stunden mit nur einer Li Ion 18650 betreiben können (@5V und nicht Batteriespannung).

Einen Stern Abzug gibt es dafür, das dieser Lüfter eine kleine Unwucht hat, die mich in meinem Anwendungsfall allerdings nicht stört. Ich bin mir auch nicht sicher ob alle Lüfter dieses Problem haben, ich habe es bereits bei einem Kommentar von der 12V Version gelesen, das es wohl kein Einzelfall ist.
