With a height of 65 mm instead of 37 mm and four heat pipes instead of two, the NH-L9x65 offers significantly more performance reserves than its lower-profile sibling models, while maintaining the same footprint of 95 x 95 mm. This ensures 100% RAM and PCIe compatibility on Intel-based ITX motherboards, and the cooler does not obstruct any nearby ports. Thanks to the highly optimized NF-A9x14 premium fan with PWM support for automatic speed control, the NH-L9x65 operates remarkably quietly. The package is completed with the professional SecuFirm2 multi-socket mounting system and Noctua's renowned NT-H1 thermal paste. Thus, the NH-L9x65 combines the familiar advantages of larger Noctua coolers in a compact, high-quality complete package for systems with limited space.
