Today we have in our labs a low-profile CPU cooler for home theater PCs and Small Form Factor systems, the Noctua NH-L9i. The compact cooler is compatible with Intel LGA115x based systems and has been designed to offer a better cooling performance than Intel's stock cooler that is possibly installed in your system.

The NH-L9i has a super-low profile of just 37mm, meaning that it is ideal for extremely slim cases. In addition, its 95x95mm footprint provides full compatibility with tall RAM modules and VGA cards on mini-ITX mainboards.

The cooler can be easily installed featuring Noctua's custom designed SecuFirm2 mounting system for LGA115x . Air stream is provided by Noctua's  NF-A9x14 fan, which supports fully automatic speed control via PWM to maintain cooling efficiency and quiet operation.

We should note that the NH-L9i has been designed to operate efficiently when installed in small form factor cases and HTPC environments. While it promises first class performance in its class, it is not suitable for overclocking and should be used mainly with CPUs with Thermal Power Design (TDP) of not very higher than the 65W. So make sure to check Noctua 's webpage to find out whether the NH-L9i is recommended for your CPU.

- Product features

	37mm low profile Due 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 compatibility The NH-L9i has a 95x95mm footprint that complies exactly to 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 mainboards 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 fan The highly optimized 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 Adaptor Allowing to reduce the maximum speed of the NF-A9x14 fan from 2500 to 1800rpm, the included Low-Noise Adaptor (L.N.A.) makes it possible to achieve near-silent setups using CPUs with less than 65W TDP.
	6 years manufacturer’s warranty Like all Noctua fans, the supplied NF-A9x14 features an MTBF rating of more than 150.000 hours and the entire NH-L9i package comes with a full 6 years manufacturer’s warranty.
