NH-L9i Specifications Videos Reviews Service ACCESSORIES Buy The NH-L9i is a premium quality quiet CPU cooler for Intel LGA115x/1200 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/1200 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. The NH-L9i is a highly compact, quiet low-profile 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 or CPUs that create high heat loads. Please consult our CPU compatibility list to find out whether the NH-L9i is recommended for your CPU. / Details 37mm low profileDue to the slim 23mm heatsink and the NF-A9x14 low profile fan that measures only 14mm in thickness, the NH-L9 stands a mere 37mm tall, which makes it ideal for use in compact HTPCs or Small Form Factor cases that offer minimum clearance for CPU coolers. 100% RAM compatibilityThe NH-L9i has a 95x95mm footprint that complies exactly with the Intel LGA115x socket keep-out zone. This means that it won't cause issues with chipset coolers and doesn't overhang the RAM slots, so it's fully compatible with tall memory modules. 100% compatibility with PCIe cards on mini-ITX Most Intel LGA115x based mini-ITX motherboards have the PCIe slot sitting right next to the 95x95mm socket zone. While larger coolers that exceed this zone are likely to block the PCIe slot, the 95x95xmm sized NH-L9i provides full compatibility with PCIe cards. NF-A9x14 PWM premium fanThe highly optimised NF-A9x14 premium fan features Noctua's proprietary AAO frame as well as sophisticated aerodynamic design measures. Supporting PWM for fully automatic speed control, the NF-A9x14 allows the NH-L9i to stay remarkably quiet. Low-Noise AdaptorAllowing the maximum speed of the NF-A9x14 PWM fan to be reduced from 2500 to 1800rpm, the included Low-Noise Adaptor (LNA) makes it possible to achieve near-silent setups with suitable CPUs that only create smaller heat loads. Custom-designed SecuFirm2™ mounting for LGA115x/1200The NH-L9i bundles a custom-designed, backplate-less SecuFirm2™ mounting system for LGA115x/1200 that offers extended compatibility with mini-ITX boards and makes installation easier than ever, all while maintaining the trusted SecuFirm2™ quality. NT-H1 thermal compoundNoctua's much-acclaimed NT-H1 is a pro-grade TIM solution that provides minimum thermal resistance, excellent ease-of-use and outstanding reliability. 6-year manufacturer’s warrantyNoctua products are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the supplied NF-A9x14 features an MTTF rating of more than 150.000 hours and the entire NH-L9i package comes with a full 6-year manufacturer's warranty.

Disclaimer:We create and update our compatibility lists with the utmost care. Unfortunately, mainboard manufacturers tend to change certain components and heatsinks without pointing it out by using corresponding revision names. If you run into problems while installing our coolers on one of the mainboards listed as being compatible, please don't hesitate to contact our support team at support@noctua.at.Please also keep in mind that other components such as narrow or small cases as well as memory modules with special (higher) heat-spreaders can cause compatibility-issues.For use in systems from Dell, HP or Lenovo, please note this FAQ.

Our case compatibility list helps you to quickly identify which PC cases offer sufficient clearance for which Noctua CPU coolers. The compatibility indication is based on the height of the coolers (including fans) as well as the maximum CPU cooler height specification given by the chassis manufacturer. Caution: Please note that the fans of some tower coolers (especially larger models with 140mm fans, e.g. NH-D15 or NH-U14S TR4-SP3) may overhang the RAM slots and that this can cause compatibility issues if RAM modules taller than 32mm are used. While the fans can be moved upwards to increase RAM clearance, this will increase the total height of the cooler and thus requires additional clearance inside the chassis. As a rule of thumb, if the fan overhangs the RAM, the maximum CPU cooler height specification of the case must be at least the size of the fan plus the height of the RAM minus 7mm (accounting for the height of the socket and CPU). For example, if a cooler uses a 140mm fan that overhangs the RAM and 46mm tall RAM modules are used, the max. CPU cooler height specification should be at least 179mm (140+46-7=179). For further information and instructions on how to move up the fan for each cooler model, please click the height specification link. Disclaimer: We create and update our compatibility lists with utmost care. However, case manufacturers sometimes change parts or details of their products without prior notice or explicitly indicating a revision. Therefore, Noctua cannot accept any liability, nor in any other way be held responsible, for the following compatibility information.

When modern CPUs use their turbo modes, they can (depending on the configuration of the UEFI BIOS) dissipate much more heat than indicated by the manufacturer’s TDP (Thermal Design Power) specification. Just like manual overclocking, this puts higher demands on the cooling solution. Our CPU compatibility list helps you to choose the cooler model that is best suited for a given CPU and your individual requirements as far as turbo and overclocking headroom are concerned. We classify our coolers according to the following categories: best turbo/overclocking headroom medium turbo/overclocking headroom low turbo/overclocking headroom compatible without turbo/overclocking headroom compatible with certain restrictions (see comment) incompatible (see comment)

For further information on CPUs exceeding their TDP ratings and how to configure the UEFI BIOS in order to avoid excessively high temperatures, please see this FAQ.

Please also see our general buying guide, motherboard compatibility list and FAQs for further help on how to select the best cooler for your configuration.
