17.12.2014 - NH-U9S
Test verdict: "Noctuas jüngste Sprösslinge glänzen mit den üblichen Werten des Herstellers. Hervorragende Verarbeitung und Kompatibilität, einem wirklich tollen Montagesystem, bei welchem sich so mancher Anbieter eine Scheibe abschneiden könnte und einer guten Leistungsfähigkeit." (Peter Gräber,

Test verdict: "Auch wenn es sich bei den beiden neuen Kühlern von Noctua um keine Modelle mit brachialer Cooling-Performance handelt, liegen die verzeichneten Temperaturen in einem Bereich, der einige deutlich ausladendere Konkurrenten überflügelt. Zudem muss sich vor Augen geführt werden, in welchen Einsatzgebieten die Verwendung eines derart kompakten CPU-Coolers sinnvoll ist. Die kleinen Würfel machen aufgrund ihrer großen Kompatibilität mit umliegenden Bauteilen des Systems und der besonders im Falle des NH-D9L geringen Bauhöhe vor allem in kompakten Systemen viel her." (William Zwingenberger,

Test verdict: "Teploty jsou velice dobré, je nutné si uvědomit, že Core i7-5960X je 140W procesor, který jsme navíc v OC taktovali o 22% výše oproti TurboBoost taktu." (David Ježek, Deep in IT)

17.12.2014 - NH-D9L
Test verdict: "110 mm olan yüksekliği ve 95 x 95 mm en boy değeriyle neredeyse tüm kasalara sığıyor ve 3U tip sunucularda bile kullanılabiliyor." (Gorkem Yildirim,
