Noctua NH-L9x65 CPU Cooler Review

Today I will be reviewing the Noctua NH-L9x65 CPU Cooler. Now this cooler is by far the smallest I will have tested to date. With that being said I don’t expect the NH-L9x65 to top the charts, but with Noctua I expect high quality and awesome performance against similar competition. I keep seeing the need for these compact cooler rise. The Noctua NH-L9x65 is extremely compact. The fan even sports a thin profile. One thing Noctua knows is cooling and there past reviews on here prove that! I will put the Noctua NH-L9x65 through a series of stress tests and the data will be available later in the review, so let us get to it and see what kind of results we get out of the NH-L9x65.

The NH-L9x65 is a taller, performance-enhanced version of Noctua’s 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 doesn’t 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, Noctua’s renowned NT-H1 thermal compound and 6 years manufacturer’s warranty, the NH-L9x65 fuses everything users have come to expect from Noctua’s larger coolers into a compact premium package for space restricted systems.
