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.

    28.07.2015 - Overclockers.ru NH-L9x65
    Test verdict: "Итак, модель Noctua NH-L9x65 оказалась эффективнее своего младшего собрата Noctua NH-L9i. И это вкупе с новой системой крепления SecuFirm2 делает новый кулер вкусным приобретением. Если у вас не совсем тонкий SFF корпус, разумнее будет приобрести именно его." (Антон Александрович, Overclockers.ru)

    27.07.2015 - infoBIT.pl NH-C14S
    Test verdict: "Słowem podsumowania, to, co na pewno można i trzeba zaliczyć na plus dla obu produktów, to system montażowy. SecuFirm od lat sprawdza się bardzo dobrze i mam nadzieję, że Noctua nie będzie go zmieniać w najbliższej przyszłości, bo po prostu nie ma sensu. Pod względem wydajności również jest dobrze."

    Test verdict: "Mit dem NH-C14S hat Noctua es wieder einmal geschafft, einen vorhandenen Kühler durch verschiedene Optimierungen nicht nur, was die Leistung angeht zu verbessern, sondern auch die Kompatibilität zu steigern." (Patrick Seus, mod-your-case.de)
