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: "I Noctua NH-D9L ed NH-U9S sono sicuramente un grande acquisto per chiunque necessiti un dissipatore performante per sistemi compatti senza rinunciare a buone temperature e ad una estrema silenziosità. Quest'ultima in particolare è un assoluto punto di forza, anche al massimo della sua velocità, infatti, la ventola da 90 millimetri di questi due modelli è praticamente inudibile."
