Noctua NH-L9x65, Premium Low-Profile CPU Cooler (65mm, Brown)

Pros: - Low profile - Quiet - Less RPM with better cooling than stock fan - Affordable

Cons: None

Overall Review: 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 the fan is spinning at 1985 RPM. 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.

Pros: * Very quiet Noctua fan * High quality construction, installation kit, and included thermal paste * Keeps temps low even in low profile mini-ITX cases * Enough thermal overhead to do some overclocking

Cons: * Not the best value in terms of degrees for dollar.

Overall Review: I recommend this to anyone building a high-end PC in a low profile case. If you have the room though, there are a ton of less expensive coolers that can even exceed the performance of this cooler.

Pros: - Fits mini ITX cases well. - Excellent performer - Very quiet

Cons: - Fan is kind of fugly, but I've already got another Noctua fan in my case so it fits the hearing aid/granny undies theme.

Overall Review: I bought this for a mini itx Coolermaster elite 130 case, which is really designed for water cooling so has low clearance. The max size listed in 65mm, so I wasn't sure this would fit. It did, and even with restricted airflow, I can not push my CPU (i7-2600) past 73 degrees, even after maxing it for 3 hours continuously by using folding@home. Also, my computer no longer sounds like it's going to take off when I rev the fans. The drop in noise was pretty massive, even with the case open. Great design from Noctua.

Pros: This NH-L9-65 fit inside my HP Pavilion Slimline S5704 case upgraded with an AMD 645 CPU (3.1 Ghz Quad core, 95W TDP), two sticks of RAM, and a Biostar TA-785-3G Mb. It runs much quieter and cools better than a stock AMD 8-core heatpipe cooler that was used previously. Since this computer is only used as an HTPC, it must be quiet, and this cooler fits right next to the RAM sticks and does the job quietly.

Cons: Could be cheaper?

Overall Review: A great cooler that is only recommended for applications with severely limited space.

Pros: - compact - good performance for size

Cons: - none considering intended application of product

Overall Review: cools a 3.8ghz phenom 955 in an silverstone htpc (3x120mm in , 2x80mm out) case just fine. if you're towards the top end of the TDP limit with this cooler like i am, make sure you have plenty of air exchange happening in your case. i do game on this machine sometimes, and it will get close to max temps in very long sessions in certain games, which i anticipated. if this were a more heavily used system, i wouldve tried to fit something beefier.

Pros: cpu much cooler, noctua fan seems like it will last forever

Cons: none

Overall Review: color is irrelevant. makes it more interesting if anything

Pros: Its Noctua, and keeps my i3 8350k nice and cool

Cons: none so far

Overall Review: Fits in the Silverstone ML03B HTPC Case in case anyone else was wondering.

Pros: It keeps an i5 7500 cool during gaming and normal use (normal use = 30C, gaming = 50C) while not being audibly noticeable. I've had 3 Noctua coolers before this and will continue to buy from them in the future. Their SecureFirm mounting system is probably the best I've worked with in my 10+ years of building PCs - super easy to install and a secure fit without making me feel like I'm warping my motherboard during installation. It also comes with a tube of thermal paste, which performs comparably to IC Diamond or AC MX4, from what I have seen on my PCs.

Cons: Not really enough to take off an egg, but when I opened the box a few of the heatsink fins were bent inward at the corners. I just bent them back into place.

Overall Review: Does not interfere with RAM on my B250 MicroATX board, as is advertised. It is fairly expensive compared to comparable coolers, but it comes with a tube of some pretty well-performing TIM, a low noise adapter (that can be used elsewhere on your PC) and a nice case sticker.
