Noctua - Bild

The NH-L9a is a premium quality quiet CPU cooler for AMD based HTPCs and Small Form Factor systems. At a super-low profile of only 37mm, the NH-L9a is ideal for extremely slim cases and due to its 92x114mm footprint, it provides excellent compatibility with tall RAM modules and other components on mini-ITX mainboards. The custom designed SecuFirm2™ mounting system for AM3+/FM1/FM2/FM2+ 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-L9a runs remarkably quiet. Topped off with Noctua’s renowned NT-H1 thermal compound, the NH-L9a fuses everything users have come to expect from Noctua’s larger coolers into a super-compact package for slim HTPC systems.

Caution: The NH-L9a 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 only recommended for CPUs with up to 65W TDP (Thermal Design Power). Please consult our TDP guidelines to find out whether the NH-L9a is recommended for your CPU.

    29.10.2014 - modding.fr NF-A4x10 5V
    Test verdict: "La série A n’entache en rien la réputation de Noctua, bien au contraire elle la sublime! Les performances collent proportionnellement aux dimensions des ventilateurs et avec un travail efficace sur le niveau sonore. Les optimisations présentes sur le cadre tout comme les pales, mais aussi au niveau du moteur et du roulement, contribuent à cette efficacité tant au niveau performance que sonore." (Bertrand Curras, modding.fr)
