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 ensures 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 and Noctua’s renowned NT-H1 thermal compound, the NH-L9x65 fuses everything users have come to expect from Noctua’s larger coolers into a compact premium package for space restricted systems.
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
The NH-L9x65 has a 95x95mm footprint that complies exactly to the Intel LGA115x socket keep-out zone. This means that it won't cause issues with chipset coolers and doesn't overhang the RAM slots, making it fully compatible with tall memory modules.
100% compatibility with PCIe cards on mini-ITX
Many mini-ITX mainboards have the PCIe slot sitting close to the socket zone. While larger coolers with 120mm or 140mm fans that exceed this zone may block the PCIe slot, the compact NH-L9x65 provides full compatibility with PCIe cards.
Easy access to near-socket connectors
Many low-profile coolers use larger fans or heatsinks in order to achieve sufficient cooling performance, but protruding over the socket zone, they make it difficult or even impossible to reach near-socket connectors on tightly packed ITX mainboards. Thanks to its 95x95mm footprint, the NH-L9x65 provides easy access to all connectors and components.

The cooler fits well within my Gigabyte Z390 Aorus Pro board, and doesn't obstruct the memory sockets which I think some larger coolers can.
Take your time fitting, read the instructions through before hand and follow them during.
Anyone who has built their own PC shouldn't have difficulty but it's a key component so take the time to make sure you get it right. As a bonus it came with some thermal paste, again follow the instructions and you'll be fine.
It helps if your PC case allows exposed cooler mounts under the main board, otherwise to fit this cooler you're going to be removing the board. This is a feature of good PC cases, and worth knowing about.
I would recommend this cooler for a quiet, cool, life on a non-overclocked stock processor. Wish I had just bought it from the start but you live & learn!
The Scythe is also low profile but was large enough to touch the memory on one side, and it blocked the PCI slot at the other, thus making it impossible to install a graphics card.
This comes in exemplary packaging, a sort of double box, which makes damage in transit just about impossible. It also includes a long screwdriver and thermal paste. There are two separate packages of materials, for AMD and for Intel.
It turned out to be harder than expected to release the Scythe, which made me wonder how on earth I had managed to get it installed in the first place. You have to turn the usual plastic Intel rods anti-clockwise, and in the tiny space available this is quite awkward. The contrast with the Noctua system of fastening is very striking, and I will never use a cooler with the plastic push rod system again. I was thinking of using the Scythe on another build, but after seeing the contrast with the Noctua mounting system am having second thoughts and may drop it off at a charity shop instead!
To install, you have to take everything out and lift up the main board enough to be able to fit the backplate. This is very simple, you just push the bolts up through the main board holes, then drop it back and attach the mounting strips on the top side using some knurled nuts, which you tighten up fairly gently with a cross head screwdriver. The result is a very solid mounting base.
The instructions are very clear. The mounting strips can be installed on either pair of sides, and depending which way you do it, the heat sink will be differently oriented. The difference is that the heat pipes project a few mm on two of the sides, so if space is very crowded you might need to choose one way rather than the other. It is however so compact that at least on my own installation it comfortably cleared the memory and the PCI socket whichever way it was oriented.
In terms of vertical clearance, my own installation is in a Sugo5 case, using a Silverstone power supply. This is a little larger than a standard ITX supply and projects out over the cpu. The Noctual fits with a couple of centimeters clearance under the PSU. The PSU is mounted with the fan at the top, so it vents externally through the top of the case. It also is just about silent. On the front of the case there is a large Noctua case fan, also very low noise.
I cleaned off the old thermal paste from the processor using cotton buds and surgical spirit, then finished off with paper towel dipped in surgical spirit. Apply a small heap of the Noctual thermal past in the center of the processor, then remove the plastic cover on the contact plate and drop it onto the processor.
The backplate and mounting strips are very robust, and the method of attaching the heat sink matches. There are two threaded rods which project upwards from the mounting strips. Two spring loaded sockets project downwards from the heat sink, and you attach these to the rods using a cross head screwdriver. It is not necessary to remove the fan for this, you can reach through the fan blades.
To connect, you can use the low noise adaptor. I did not bother and doubt it will be necessary for many people. The reason I didn't is that the processor is a little out of spec for this cooler, high by about 12 watts.
Its now mounted with plenty of space around it for access to the rest of the board, and the questions are noise and temperature.
In terms of noise, its just about inaudible. I am not doing any very demanding graphics work or anything that will really stress the processor, but in normal use of office or home media applications its inaudible. So far its never risen to any audible level.
Cooling is exemplary. Its at least as good as the Scythe, and quieter with it. Temps at idle are in the high thirties, rising to the low forties on one or two cores in use, and as I say, in just about complete silence. Writing this for instance the hottest cores are 38 and the cpu fan is at zero.
If I were assembling an ITX today, I'd, get a Silverstone 13 case, mount the biggest Noctua fan it will take in the front, use a 35 watt processor, a smaller power supply, and cool it with one of these. It will be silent and low power and will last forever.
Reservations? None. There is a comment in these reviews that the supplied screwdriver is chromed down to the tip, and that small bits peel off in use. It is indeed chromed, and just to be safe I used a standard cross head screwdriver with bare metal tip in most of the installation, but I used the supplied on on a couple of the heads with no problem. To anyone considering this I would say just get it. Its a real quality item, does exactly what its supposed to, well designed and built and great performance.
G Skill Trident Z memory..
The first cpu cooler I waited four days to arrive..
I ain't gonna say what it was cos I ain't even gonna advertise something that failed.. The review said it would work.. But seems there are folk that like to put up faked reviews..
Complained to Amazon an got instant refund.. Impressed.. Then ordered this an it arrived at 10:00am the following day.
Took five minutes to install.. Then probably fifteen minutes admired..
So this works 100% on new Am4.. Plus ya get fitting for older AMD.. An Intel..
Plus a nice long screwdriver..
It's super quiet..
Keeps my temps down..
I am now the biggest fan of Noctua products...
Simple to install, used on a small form factor build to cool an i7 9700 with a TDP of 95w. Without overclocking its running 40c idle at 50% fan and 70c at 100% fan pushing 120 frames per second of first person shooter.
Awesome performance from something so small. Would buy again and recommend to a friend.
All that is gold does not glitter, and the retro beige fan is like a statement of form follows function.
Its almost touching the NAS bays restricting airflow but still keeps the CPU under 86C under a 100% 24/7 load (Folding at Home), especially considering the airflow constraints of the case. A bonus feature is this airflow restriction forces more air over the HDDs, dropping their temperatures by 5-10C.
