Noctua NH-L9i Chromax Black ultra low profile cpu heatsink noctua nh-l9i is an all-black version of noctua's award-winning nh-l9i cooler for htpc build and small form factor (sff); thanks to the same proven design and pwm nf-a9x14 fan, it stays true to the successful formula of the nh-l9i of melting a height of only 1.457 In with high performance and excellent quiet operation, as well as 100% RAM and pcie.the chromax version. Black with total black fan and heatsink, combines the functional elements of the previous version with a more elegant and understated appearance; to complete the offer, the renowned secufirm2 low-profile mounting system for intel lga115x and noctua's NT-H1 thermal paste.award-winning NH-L9Idecine cooler thousands of enthusiastic users around the world are satisfied with the quality and the performance performance nh-L9i; recommended by over 150 international hardware websites and magazines, is renowned for being one of the best low profile coolers on the market.It's a highly compact low-profile silent cooler designed for use in small form factor and htpc cases; while offering top-notch performance in its class, it is not suitable for overclocking and should be used with care on CPU with tpc dp more than 6 and 5w (thermal design power); see our CPU compatibility list and tdp guidelines to find out if the nH-L9i is recommended for your cpu.l'nh-l9i chromax. Black is full blacki, equipped with a black coated heatsink, a black fan with black anti-vibration pads, black fan screws and black mounting parts, is perfect for all-black constructions and easy to match with other color combinations.37mm low profiles to the slim 23mm heatsink and nf-a9x14 low-profile fan measuring only 0.9x14 551 in Thick, the NH-L9 has a height of only 37mm, making it ideal for use in compact htpc or small form factor cases that offer minimal space for RAM cpucompatibility coolers 100% the NH-L9i compatible with any RAM memory kit due to its extremely small dimensions (95x95mm lat. o); this means you You will have no mounting problems on any configurationFull compatibility with pci-express boards on motherboard mini-itxMost mini-itx motherboards for intel lga 115x feature the pci-express slots near the processor socket; using normal size heatsinks not uncommon to run into serious problems that affect the assembly of our hardware; with the noctua nh-l 9the compatibility 9i the compatibility Instead, ensuring the mounting of any card on pci-express.nf-a9x14 pwm premium fanla fan nf-highly optimized a9x14 premium offers proprietary aao noctua frames and sophisticated aerodynamic design measures; support PWM for fully automatic speed control, the NF-A9X14 allows NH-L9i to remain particularly silent. osolow-noise Adaptoril low-noise adaptor (lna) included in the package allows to reduce the rotation speed of the nf-a9x14, ideal solution for all configurations with processors with maximum absorption of 65w.custom-designed secufirm2 mounting for lga115xil coupling system, thanks to noctua's secufirm 2 technology, allows you to install the cooler on intellectual lga115x socket. and Award-winning and certified, it allows a fast and stable installation in every conditionent-h1 thermal compound, a thermoconductive paste that offers minimum thermal resistance, excellent ease of use and reliability. The NT-H1 maintains its thermal transfer capacity unchanged throughout the thermal arc, from -50 to +110c, a feature that makes it ideal for the most demanding users. 6 years: products products and products and products are Renowned for their impeccable quality and exceptional longevity; like all noctua enthusiasts, the NF-A9X14 features a MTBF of over 150,000 hours and guarantees this product for a good 6 years; welded interface between heat pipes and fins with many heat sinks, the fins are pressure mounted on the heat pipes; due to the different coefficients of thermal expansion copper and aluminthis Adaptation can loosen for years of thermal cycle, resulting in performance reductions; in contrast, the fins of the NH-L9I are welded to the heat pipes to ensure a superior thermal interface that will not deteriorate even after many years of use.
