Noctua - Bild

The NH-L9i is a premium quality quiet CPU cooler for Intel LGA115x based HTPCs and Small Form Factor systems. At a super-low profile of only 37mm, the NH-L9i is ideal for extremely slim cases and due to its 95x95mm footprint, it provides full compatibility with tall RAM modules and VGA cards on mini-ITX mainboards. The custom designed SecuFirm2™ mounting system for LGA115x makes installation a child’s play and thanks to the highly optimised NF-A9x14 premium fan that supports fully automatic speed control via PWM, the NH-L9i runs remarkably quiet. Topped off with Noctua’s renowned NT-H1 thermal compound, the NH-L9i fuses everything users have come to expect from Noctua’s larger coolers into a super-compact package for slim HTPC systems.

Caution: The NH-L9i is a highly-compact low-profile quiet cooler designed for use in small form factor cases and HTPC environments. While it provides first rate performance in its class, it is not suitable for overclocking and should be used with care on CPUs with more than 65W TDP (Thermal Design Power). Please consult our TDP guidelines to find out whether the NH-L9i is recommended for your CPU.

    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, HT4U.net)

    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."

    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)
