A great cooler for my mini-ITX build in a Lian Li PC-Q03 case. Keeps the i5–8600 cool in this tiny case with no case fans. I've modded the PSU with a 3000rpm 120mm noctua pwm fan fed off the evga motherboard and flipped the cpu fan upside down so it blows directly into the psu fan. This throws the cpu heat right out the psu vent, the 3000rpm gets noisy as it's rejecting heat from the GTX1070 jammed in there too. The NH-L9×65 keeps the CPU under 65C (mostly) in SWBF2 at ultra settings. The GTX1070 needs some more air so the hole saw is coming out soon to let more air into the fan intake.


The NH-L9×65 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-L9×65 is more powerful than its smaller siblings yet retains their 95×95mm 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-A9×14 premium fan that supports fully automatic speed control via PWM, the NH-L9×65 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-L9×65 fuses everything users have come to expect from Noctua’s larger coolers into a compact premium package for space restricted systems.

Caution: The NH-L9×65 is a highly-compact low-profile quiet cooler designed for use in small form factor cases and HTPC environments. While it provides first rate performance in its class, it is not suitable for overclocking and should be used with care on CPUs with more than 84W TDP (Thermal Design Power). Please consult our TDP guidelines to find out whether the NH-L9×65 is recommended for your CPU.
