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.

    21.11.2014 - OCDrift.com NH-D15
    Test verdict: "There’s no doubting that the Noctua NH-D15 is a very decent air cooler. Noctua improved the shortcomings of the old flagship cooler NH-D14 by expanding the dual tower design and offer a much better memory compatibility, which allows for more memory kits with high-profile heatspreader to sit under the heatsink. The build quality is excellent with the heatsink’s aluminium fins soldered nicely onto the heatpipes. The SecuFirm2 mounting kit makes cooler installation easier and more secured."

    21.11.2014 - 59hardware.net NH-U14S
    Test verdict: "Il est tout d’abord apparu que le NH-U14S est un ventirad très bien conçu et qui doit être produit selon des canons très stricts, c’est tout du moins l’impression qu’on a en considérant sa qualité de fabrication générale. Puis, la phase de montage s’est montrée aussi facile que dans le cas des autres ventirads Noctua (et pour cause) et relativement rapide. Quant aux performances en refroidissement, elles sont, comme toujours pour l’instant chez Noctua (après trois tests plus que concluants), elles sont au-dessus de la mêlée et le tout dans un silence plus que relatif, à la hauteur de la réputation que le constructeur s’est patiemment forgée au fil des années."

    Test verdict: "Noctua iPPC modele možemo preporučiti svima i za skoro sve namene, a da ne bismo previše odlutali od IT domena, vratićemo se na računare i performanse." (Atila Gobor, PCAXE.com)
