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.

    20.10.2014 - TechTesters NH-L12
    Test verdict: "De NH-L12 is net als z’n broertjes en zusjes bedoeld is als een product voor echte liefhebbers die graag iets meer uitgeven om net die beetje extra prestaties te halen, of die de typische Noctua-ervaring reeds waarderen, en met dat in het achterhoofd doet de NH-L12 het zoals verwacht uitstekend."

    19.10.2014 - bcchardware.com NH-D15
    Test verdict: "True to Noctua form, the NH-D15 is virtually silent - and the volume level is even quiet managable at 100% fan speed (~1500rpm). The cooling performance of this monster actually bests all but two of the liquid cooling systems and every other heatsink we tested." (Benjamin Heide, bcchardware.com)
