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.

    Test verdict: "Dans l’ensemble, les deux sont excellents !" (Godin Charles,

    06.10.2015 - Always More Digital NH-C14S
    Test verdict: "В итоге кулер Noctua NH-C14S получился весьма неплохим и заслуживает того, чтобы на него обратить внимание при покупке, пусть даже по современным реалиям его цена будет «кусаться», так как его рекомендованная стоимость равна 74,90 доллара." (Zastavnoy Mikhail Ivanovitch, Always More Digital)

    06.10.2015 - NH-C14S
    Test verdict: "Kto powinien zatem zainteresować się C14S? Na pewno posiadacze wydajnych procesorów po optymalnym OC, zamkniętych w wąskich obudowach, a także do wysokich radiatorów RAM-u. To główna zaleta konstrukcji, choć kusi także 6-letnia gwarancja." (Kamil Homziak,

    06.10.2015 - NH-D15S
    Test verdict: "Ter algo como o NH-D15S é ter a supremacia máxima em dissipadores de computadores com troca de calor a ar." (Carlos Xandelly,
