Noctua NH-L9x65 chromax.black 65mm Low Profile CPU Cooler

Performance:excellentBest Feature:quietProduct Quality:excellentShaved off arround 10degrees in my temps. Naka sff build ako gamit ung phanteks evolv shft xt, napakainit na case. Haha.Premium yung price but so far mganda nman performance. Will update this if with problem.1st time noctua product ko to.

Awesome low profile cooler

I put this in to a Fractal Terra case based media machine, which would allow for this units taller 65 mm height. Performance is amazing. No one in my house can hear the fan when the media machine is powered on, and temps are showing as very low. Exactly what I expected from a Noctua HSF.

Great Cooler!

I am using this on a 10600k and it idles around 28C, will hit 55C to 60C under load. So works for cooling. What really impresses me about Noctua coolers in general, I have several others, is how well engineered they are and how well thought out the product is. The directions provided are excellent and the design is such that install is super easy, significantly easier than other brands I have used. I tried my first Noctua cooler last year and wished I would have tried them sooner. They are the best I have found.

Great cooler, but NOT for 2U server!

I bought this for a build in a supermicro 847 storage server chassis. Several reviews stated it fits in a 2U enclosure, but this is a lie. I mean it technically fits, but there is maybe 1/4" between the fan and the top of the case, so it's seriously starved for air. I was hitting 90C with the CPU barely working. I ended up cutting a hole in the top of the case so the cooler could breathe. With access to fresh air, CPU temps plummeted and now it barely hits 70C, even at max load. If you're building in a 2U chassis, just save yourself the headache and get the L9i instead.

Nice Low Profile Fan!

I'm using this fan with the i3-6100 Skylake and an ASRock Z170M-ITX/ac motherboard. To begin, this fan does fit this ASRock motherboard, but barely. Though the fan is not forcefully pressing on the RAM stick, it certainly does look like it is touching it or perhaps there is literally only thousands of an inch of space between the two. In my system, this fan cools the i3 Skylake up to 5-6 Celsius cooler with about 500-600 RPMs less than the stock fan. My results are based on ASRock's A-Tuning software that came with the motherboard. Also, the stock fan shipped with the i3-6100 Skylake is noticeably louder. Obviously, if you are gaming with this fan, RPMs will increase depending on temperature. As I am typing this review, A-Tuning tells me the CPU temp is 24C/75F and ... MoreI'm using this fan with the i3-6100 Skylake and an ASRock Z170M-ITX/ac motherboard.

For those who are wondering if this Noctua fan will fit your mini-ITX case or other low profile/thin case, be aware that you will need at least 4 1/4-inch wide case to fit this fan. Preferably, the case should be about 4 1/2 inches and up for this fan. This fan will NOT come close to fitting in the Mini-Box M350 case, which I have. It will also NOT fit the Morex T3500 mini-ITX case, which I have. I purchased the In Win Case IW-BM639.AH160TB Black Mini-ITX case for this fan, which has sufficient room and is the smallest case that I know of that will fit this fan, which is 4.4 inches wide. This fan comes with thermal paste, which I am using. There is enough paste for a couple of tries. As far as price, you know what they say: "You get what you pay for!" Overall, I am very happy with this fan.

Noctua did their homework on this.

The best costs a little more, but you don't have to buy it twice. I build HTPCs and for this purpose a computer has to run cool and be quiet. No one should hear a cooler speed up and slow down while they're streaming a movie, playing a game or watching a Blu-ray. I've tried other coolers that claimed to be quiet, but weren't. I'd read that Noctua prided itself on being effective and quiet, so I tried this cooler. I no longer need to wonder how loud the CPU cooler will be when I start a build for the first time, it's a little more expensive, but a predictable positive result is worth it. The packaging is a work of art and brute squad proof. For my AMD processor, installation was easy, with clear instructions. Everything you need for installation, including a narrow ... MoreThe best costs a little more, but you don't have to buy it twice.

It may cost a little more, but when you're done and you look at the computer you just built, you know it'll be quiet and it has a really good cooler in it.

Ok for casual use | Can't recommend for gaming

i7-2600K (LGA 1155) - When idle, browsing/surfing or doing various office work the temp is around 45-50°C. - When the tasks become more CPU intensive like updating/installing drivers/apps or scanning, the CPU's temp will rise around 60-70°C. - If you wanted to play games, well you can forget about that using that heatsink with the i7-2600k... It just can't dissipate the heat fast enough and you will hit above the critical temp recommended by Intel which is 72°C. Tested mostly by playing Overwatch, Doom, Battlefield 1 & V and well the CPU's temp was always around 70-75°C and stayed above 72°C when playing for a prolonged time. Depending on what you are looking for, it can do a decent job but as soon as you want something a little bit more intensive I would advise to ... Morei7-2600K (LGA 1155) - When idle, browsing/surfing or doing various office work the temp is around 45-50°C. - When the tasks become more CPU intensive like updating/installing drivers/apps or scanning, the CPU's temp will rise around 60-70°C. - If you wanted to play games, well you can forget about that using that heatsink with the i7-2600k...

I just can't recommend it. Noctua is generally a really good investment but not for this pairing.

Tidy Low Profile Cooler

In a space limited case (Lian Li PC-CK101) my options were very limited and very few CPU Coolers would fit. A look at the compatibilty charts on the Noctua Website lead me to this Cooler. It was easy to fit, not having access to the rear of the ITX Mainboard I needed to remove the board to fit the supplied backplate. The instructions were clear although a little care was needed to select the right spacers from the selection provided.Performance wise this Cooler was a lot better than the standard Intel one on my setup; under full load (Prime 95) the Intel heatsink couldn't cope and the CPU throttled, with the Noctua it was around 20 Degrees Centigrade cooler and never got close to throttling.The 15mm supplied fan is a trifle noiser than usual for a Noctua Fan ... MoreIn a space limited case (Lian Li PC-CK101) my options were very limited and very few CPU Coolers would fit.

Typical Noctua Quality, Easy to Set Up, Great for Server and SFF Builds

This cooler is working beautifully on my recently-updated firewall in 3U rackmount case. The cooler on the old board (an AM2+ Athlon64 X2) crapped out and the CPU and RAM on that board was a bit too under-powered to handle the amount of traffic flowing through the gateway, so I ended up swapping some boards around to replace it with an older-model Intel quad-core. Unfortunately, the Noctua cooler that had been on the replacement board/CPU wouldn't fit in my 3U case so I needed something new. The HN-L9x65 fit perfectly on the old Noctua mount (so I didn't even have to replace the backplate) and easily fits in the case (I think it'd even make it in a 2U case, though I haven't measured). Perfectly quiet and given the longevity of Noctua fans, I expect it to run for ... MoreThis cooler is working beautifully on my recently-updated firewall in 3U rackmount case.

Perfectly quiet and given the longevity of Noctua fans, I expect it to run for years and years without trouble. I think I might even pick up another one to resurrect the AM2+ board (if it will fit in a 2U case) and give that a second life as a small Linux server.

Works with HP M01-F1024 prebuilt

At first, I thought I had made a big mistake when I bought this. After I pulled out the motherboard from the prebuilt machine, I saw that the backplate was glued on. After hearing about a possibility, I decided to try and carefully remove the backplate. After a slow process, I managed to pry the backplate off and was able to install the heatsink. There is enough height to clear the capacitors all near the CPU. I used the included thermal paste and temps are a few degrees cooler (don't have exacts) while also being much quieter.
