The NH-D9L is a premium grade dual tower CPU cooler that has been designed to provide excellent quiet cooling performance at a height of only 110mm. Its comparably low profile (15mm lower than classic 9cm tower coolers such as the NH-U9S) doesn't only ensure full 3U compliance but also makes the NH-D9L ideal for compact HTPC and Small Form Factor cases that have airflow paths parallel to the mainboard. Thanks to its 95x95mm footprint, the NH-D9L clears the RAM and PCIe slots on all Intel based and most AMD based ITX mainboards. The included NF-A9 premium fan supports automatic speed control via PWM for outstanding quietness of operation and a second, optional NF-A9 fan can be added for further improved performance in dual fan mode. Topped off with the trusted, pro-grade SecuFirm2 multi-socket mounting system and Noctua's proven NT-H1 thermal compound, the NH-D9L forms a highly compact premium package for space-restricted applications.

Low-profile tower design with 3U compatibility
While most low-profile coolers blow air towards the motherboard, the NH-D9L is a tower style cooler that blows parallel to the mainboard, which allows for superior airflow efficiency in cases with front intake and rear exhaust fans that create an airflow path parallel to the mainboard. The NH-D9L's reduced height of 110mm also allows it to fit 3U chassis. This makes it ideal for noise-sensitive 3U applications in fields such as audio or video processing.  
100% RAM compatibility
With its 95x95mm footprint, the NH-D9L does not overhang the RAM slots on current Intel and most AMD mainboards. This gives the user full access to the memory modules and ensures 100% compatibility with tall heatspreaders or optional memory fans.  
100% compatibility with PCIe cards on mini-ITX

NT-H1 thermal compound
Noctua's much-acclaimed NT-H1 is a pro-grade TIM solution that provides minimum thermal resistance, excellent ease of use and outstanding reliability. Chosen again and again by overclockers and enthusiast users worldwide, it has established itself as a benchmark for premium-quality thermal compounds.
