"The response on our first low profile cooler, the NH-L12, has been overwhelming", says Mag. Roland Mossig, Noctua CEO. "However, users asked for even smaller, lower height models that also provide better compatibility for extra slim, ITX based HTPCs. We're thrilled that we can now meet this demand with the new NH-L9 coolers."The NH-L9i and NH-L9a are premium quality quiet CPU coolers for Intel LGA115x (NH-L9i) and AMD FMx (NH-L9a) based HTPCs and Small Form Factor systems. Due to the slim 23mm heatsink and the NF-A9x14 low profile fan that measures only 14mm in thickness, the NH-L9 coolers stand a mere 37mm tall, which makes them ideal for use in compact HTPCs or Small Form Factor cases that offer minimum clearance for CPU coolers.

The heatsinks have a 95x95mm (NH-L9i) and 92x114mm (NH-L9a) footprint that complies exactly to the Intel LGA115x and AMD FMx socket keep-out zones. This means that the coolers are fully compatible with tall memory modules and PCIe cards on mini-ITX mainboards.

The 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-L9 coolers to stay remarkably quiet. The included Low-Noise Adaptor (L.N.A.) allows to reduce the maximum fan speed from 2500 to 1800rpm and makes it possible to create near-silent setups.

The NH-L9 coolers bundle custom-designed SecuFirm2™ mounting systems for AMD FM1/FM2/AM3+ (NH-L9a) and Intel LGA1150/1155/1156 (NH-L9i) that offer extended compatibility with mini-ITX boards and make installation easier than ever, all while maintaining the trusted SecuFirm2™ quality. The premium quality bundle is completed by Noctua's much-acclaimed NT-H1 thermal compound, a well proven pro-grade TIM solution that provides minimum thermal resistance, excellent ease-of-use and outstanding reliability.
