Noctua NH-D9L, Premium CPU Cooler with NF-A9 92mm Fan (Brown)

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) doesnt 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 Noctuas proven NT-H1 thermal compound, the NH-D9L forms a highly compact premium package for space-restricted applications.

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.
