Yes, Noctua's thermal compound is included in the package as a "syringe."
To mount the backside bracket, you'll almost certainly need access to the motherboard's backside/bottom. I didn't have to remove the motherboard because my chassis had an access panel; see if you can remove the panel that faces the backside of the motherboard.
Height : The difference between 160mm (d15s) and 110mm (d9l) is significant. (protruding from the motherboard) about 2 inches shorter: http://www.br>br>br>br>br>br>b //noctua. at/en/nh- d9l/description
Selected User Reviews For Noctua NH-D9L, Premium CPU Cooler with NF-A9 92mm Fan (Brown)
The Dell XPS 8940 with 65 watt CPU does not have studs for mounting this cooler; instead, it has M3 female flush with the motherboard, which requires M3x20mm screws or M3x25mm ser screws (to use provided nuts) to mount this cooler on the 8940 motherboard. Installation is a breeze with these additions. br>br>According to some reviewers, mounting the cooler to the brackets was a challenge. The cooler's (4/2021) instructions state that the fan must be removed before the cooler can be installed. After the cooler is mounted, the fan simply clips back on.
D9L with an i7 8700K that has not been overclocked. I also have a computer with an i7 8700 (non-Kaby Lake) processor. K) with no overclocking and an Intel stock cooler. Both computers were built around the same time and have added fans to their Cooler Master HAF 912 cases. Both computers are in a room with a temperature of 73 degrees Fahrenheit. Core Temp 1 was the application I used. All temperatures are in Fahrenheit and are rounded to the nearest hundredth of a degree. br>br>For a few hours, the CPUs in both computers were heavily used, transcoding video with Handbrake. Although the transcoding uses GPU encoding, Handbrake continues to use the CPU at any rate between 40% and 100% depending on the video source. The Noctua's 8700K temperature ranges from 118 to 150 degrees, with a high of 158 degrees. The stock Intel cooler on the 8700 runs around 130° to 180° (usually at the high end of the range), and the highest temperature recorded was 212° (the maximum temperature for this CPU). I wanted to see if the Noctua was truly superior to the stock Intel cooler, so I put them to the test today. It's a significant distinction! br>br>As an aside, this cooler was simple to set up. The cooler's mounting to the motherboard was the only minor issue. Make sure one side is barely threaded before moving on to the other. If you tighten the first side even slightly, you might have trouble threading the other side. That was the only stumbling block. The rest went according to plan. br>br>Because it wasn't made of copper, I had my reservations about it. I didn't expect it to cool down as quickly as it did. The metals used appear to be capable of dissipating heat. When I first turned it on, the fan seemed a little weak, which worried me, but the temperatures are impressive. br>br>I'm glad I compared CPU temperatures today because the i7 8700 with the stock cooler is running way too hot. I placed a second order for a Noctua NH- The stock cooler is being replaced with a D9L. This CPU cooler is well worth the money. br>br>UPDATE 11/2/2018br>br>I purchased another one of these coolers for my computer, which has an Intel i7 8700 (non-Kaby Lake) processor. K) because while transcoding video I saw average temperatures ranging from 180° to 185° F (and not with the CPU pegged at 100%). Even with the room air conditioner set to 73 degrees F, this was the case. I installed the Noctua CPU cooler today, and I'm transcoding video without using the room air conditioner because the temperature is around 75 degrees Fahrenheit. So far, the highest temperature I've seen is 180° F, and this CPU previously reached a maximum temperature of 212° F using the stock cooler. Currently, the average temperature I'm seeing while transcoding video is between 140° and 165° F, depending on CPU usage. I decided to max out the CPU with another instance of Handbrake, but this time without GPU encoding, and that's when I noticed the 180° high. This is what I saw with the stock cooler when the CPU was not maxed out for extended periods of time. This CPU cooler has exceeded my expectations. br>br> Even when I hammer my CPU, I notice a 15° to 20° drop in temperature.
91W at 7700K. On full constant loads with no OC, the smaller one hit 100C and thermal throttling, but it still worked fine for normal use and games. In an ITX case setup, this one will barely reach 80C on full constant load with no OC. The only issue is that it comes with extra brackets for a second 92mm fan, but they are only compatible with the thicker fans, not the thinner 92mm fans that I had on my other CPU cooler and had hoped to use in conjunction with the one it comes with. Noctua continues to produce superior air cooling products, and this one includes a top three rated CPU paste as well as all of the metal tools and hardware needed for installation. This is my third Noctua cooler, and they always perform as expected. However, before you choose a CPU cooler, I recommend that you visit the Noctua website and read their TDP guide to ensure that you get the right one for your needs. Helped me find the right cooler for my processor while staying within my space constraints.
Very well built, quiet as a whisper, and cools just as well as my previous water cooling setup. It's simple to put together and sturdy. I was a little disappointed that the temperatures didn't drop as much as others had claimed (they stayed the same, whereas others reported getting down to 30 degrees or so at idle and no more than 45-degrees at maximum load). (Under load, 50 degrees). It idles at around 36 degrees for me with my i7 4790K (not overclocked), and it gets up to around 70 degrees under load, sometimes 75 degrees. The airflow is handled by six other Noctua fans in an ATX tower. As a result, it's roughly equivalent to liquid cooling. The fact that it is quiet and occupies less space is a major plus. br>br>With Noctua products, you can't go wrong. I'm not sure what's causing my temperatures to be so much higher than other people's. However, I am aware that the 4790K runs hotter than other i7s, so I attribute it to that. As previously stated, this corresponds to liquid cooling temperatures, takes up less space, and is completely silent even at its highest fan speed. So, in my opinion, it's a winner. I now have a massively powerful gaming rig that is silent even when gaming, thanks to the replacement of all my case fans with Noctua fans and the installation of a STRIX GTX 960 graphics card (fans don't run unless it's being worked hard).
