The NH-L9x65 is a taller, performance-enhanced version of Noctuas award-winning NH-L9 low-profile coolers. With 65 instead of 37mm height and four instead of two heatpipes, the NH-L9x65 is more powerful than its smaller siblings yet retains their 95x95mm footprint, which guarantees 100% RAM and PCIe compatibility on Intel based ITX mainboards and makes the cooler more convenient to work with as it doesnt overhang near-socket connectors. Thanks to the highly optimised NF-A9x14 premium fan that supports fully automatic speed control via PWM, the NH-L9x65 runs remarkably quiet. Topped off with the professional SecuFirm2 multi-socket mounting system for Intel and AMD, Noctuas renowned NT-H1 thermal compound and 6 years manufacturers warranty, the NH-L9x65 fuses everything users have come to expect from Noctuas larger coolers into a compact premium package for space restricted systems.Specification:- Dimensions: Without fan: 95 x 51 x 95 mm (W x H x D).
