Product line:

Not suitable for CPUs that create high heat loads. Check CPU compatibility before purchase!

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.

“The Noctua NH-L9x65 may have some cooling limitations in extreme overclocking conditions but if you have limited space and are in need of a cooler that can handle the stock load, look no further because the Noctua NH-L9x65 will meet those demands!”

“[T]he Noctua NH-L9x65 is a great option for anyone building a small form factor PC who needs the higher TDP when compared to the NH-L9a/I or if you just want a little room for overclocking. I don’t think you are going to find a better option in the f...”

“Unter den kompakten Top-Blow-Kühlern mit 92-mm-Lüfter ist der Noctua NH-L9x65 schon regelrecht ein Riese, bietet dafür aber gegenüber der flacheren Konkurrenz auch mehr Performance. Solange ausreichend Platz vorhanden ist, ist er aus dem frisch getes...”

“There’s a lot to love about this cooler, and while I admit that it’s certainly not suitable for everyone’s needs, there’s a big market for very small coolers and the NH-L9x65 is one of the best in its class by a rather large margin. Capable of coolin...”

“Noctua revives what a compact cooler can be! The NH-L9x65 can tame our beast, comes with rock solid mounting hardware, and comes in at a fairly good price.”

NextHardware.com•Alfonso Basilicata

“Come al solito le prestazioni sono convincenti, considerato che il dissipatore in questione è di tipo top flow (a sviluppo orizzontale) ed è stato creato appositamente per sistemi estremamente compatti.”

“Le NH-L9x65 est un ventirad « taillé » pour les mini boîtiers, les HTPC et toute sorte de boitier où la place est comptée.”

Key features

65mm low profile

Due to its compact heatsink and the 14mm thin NF-A9x14 low profile fan, the NH-L9x65 stands only 65mm tall (the same height as low-profile expansion cards), which makes it ideal for use in compact HTPCs or Small Form Factor cases that offer limited clearance for CPU coolers.

100% RAM compatibility

With its compact 95x95mm footprint, the NH-L9x65 does not overhang the RAM slots on Intel LGA1851/LGA1700/LGA1200/LGA115x and AMD AM5/AM4 based motherboards, which ensures easy access to the modules and 100% compatibility with DIMMs that feature tall heat-spreaders or RGB lighting.

100% compatibility with PCIe cards on ITX

Many Intel LGA17xx/1200 based mini-ITX mainboards have the PCIe slot sitting close to the 95x95mm socket zone. While larger coolers that exceed this zone may block the PCIe slot, the 95x95mm sized NH-L9x65 provides full compatibility with PCIe cards.

NF-A9x14 PWM premium fan

The highly optimised NF-A9x14 premium fan features Noctua's proprietary AAO frame as well as sophisticated aerodynamic design measures. Supporting PWM for fully automatic speed control, the NF-A9x14 allows the NH-L9x65 to stay remarkably quiet.
