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 NH-L9x65 jest lepszym rozwiązaniem, niż model L9a. Ma zdecydowanie lepszą wydajność i podobną głośność. Oba produkty posiadają taki sam wentylator, który jest dość cichy podczas pracy na komputerze." (Paweł Borysewicz, videotesty.pl)

    Test verdict: "Tirare delle conclusioni su questo genere di proposte non è mai semplice, se però si analizzano le premesse con il quale l'NH-L9x65 viene venduto possiamo sicuramente direi che il bersaglio è stato nuovamente centrato da parte di Noctua." (Damiano Villa, CoolingTechnique.com)

    Test verdict: "Noctua is in a great place market wise, because of good performance and quality fans. Any users who either do not have the internal retail space or is looking for lower temperatures versus using the stock cooler. This is what this cooler is intended for. It may be a little pricey for my taste, but you get a lot for what you pay." (Isaiah Rossiter, OverclockersClub.com)
