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: "Noctua’s NF-A14 FLX, NF-A14 ULN, and NF-A15 PWM are all excellent fans. They are virtually inaudible yet manage to retain excellent airflow and static pressure, and are backed by the reliability of the Noctua brand." (Mike Lewis, Reliable PC Reviews)

    23.05.2013 - pc-overware.be NH-L9i
    Test verdict: "Ce que nous pouvons dire c’est que ce petit Noctua sera le compagnon idéal des cartes mères mini-itx couplées à un processeur Intel à faible consommation et placées dans un boitier exigu. Il s’adressera aux perfectionnistes exigeants quant à la qualité des composants de leur système. Des systèmes Home Cinéma principalement, mais aussi un petit serveur ou un nettop."

    22.05.2013 - CoolingTechnique.com NH-U12S
    Test verdict: "Le nuove soluzioni di raffreddamento a marchio Noctua si dimostrano più come un passo avanti nella tecnologia dell'air cooling piuttosto che come la solita minestrina riscaldata a cui ormai ci stanno abituando da qualche tempo a questa parte."
