Noctua NH-L9i, Premium Low-Profile CPU Cooler for Intel LGA1200 & LGA115x (Brown)

I was building a custom NAS, I purchased a used mini ITX mobo. The fan that came with it worked, however it was extremely loud and I had to quiet it down. From my previous experience I knew I had to replace the drive caddy fan and the CPU cooler fan with Noctua versions. I was impressed with the massive change in the sound of the NAS currently. The loudest noises now come from the hard drives!I am currently using this to cool an i7-4790 that is generally running near idle unless I am running VMs. The fans barely move and yet the temperature never goes above 30°C.Pros:-Extremely low/no noise from fans-95x95 mm size allows for small dense mobos that have extrusions near the CPU.-37mm height means you can fit it in small cases and is really useful if you are designing/building your own case-Noise conscious; the fan has rubber feet, the fan is properly balanced, the fans have aero features to help limit noise-LNA cable if you really want it to be quiet, in multiple builds I have yet to find a need for this though-Good performance, putting this cooler on decreased my CPU temps by 2 to 5 degrees compared to the cheap one that came on my used moboCons:-Price is higher than other options, but this is a high quality cooler-The fan does bring in air from the top, which may make some use cases finickyOverall: I would recommend this cooler if you are in need of a low profile silent solution to keeping your temperatures in check.

Best low profile cooler I have ever brought.Firstly Noctua is known for there amazing products. I was going to buy the recommended Cooler Master 130 case suggestion then seen this.The design is pure gold for spacing in a micro itx case. You don't have to worry about ram size or hitting the GPU. It actually makes cable management easier with the saved space.I was confused by no brackets no brackets includeded for all the different cpu styles then realized this is strictly for the LGA 1151, which it fit like a glove.I coupled it with some ARCTIC MX-4 Thermal Paste, which I have been using in my builds for years, basically since it came out. Easiest paste to install and way better than many other brands.Noctua does include thermal paste, some quiet cable, some screws, and a badass little metal sticker in the box.The only thing I wish that they would do is have spacing around the fan corner for cable insert for better management. you can either run it under the heatsink since wire is thing or just up above tied off. Little grooves on corner to catch it would of been cool though.Temps wise I have yet to go over 54c on a single core, for gaming/benchmarking my GPU(Heaven/FurMark used). I haven't stress tested the CPU but I also have no reason to since this is primary for gaming. I am very happy to be anywhere under 60c while gaming.

First comment, this cooler kicks-ass!! I installed it into a "Cooler Master Elite 120 Advanced - Mini-ITX". The fit to most ITX motherboards will seem snug to many people, however the Noctua works very well. People who are new to the ITX world are going to have to get accustomed to a new way of doing computer builds. The Noctua does come very close to many parts on the mobo, however, that is a choice one has no control over if one wants to install a top of the line Processor with a High End video card,high end RAM and plans on having a proper power supply run it all inside an ITX container.I was thoroughly impressed with how well the product was shipped. All the parts are separated and snugly fit into a rubber/foam material. It also comes with a tube of thermal paste (The heatsink does not have any pre-applied thermal, awesome). This allows you to do a "dry" install to make sure the fan will fit properly for your motherboard. The ease of install is 10 out of 10. YES, It requires having access to the bottom of the mobo (like a proper heatsink does). What I liked the most is that there is NO pain in the ass rear mounting plate. You simply bring the screws up from the bottom and twist them into the heatsink.The fan is quiet and can ramp up quite well when needed.I have an Intel i5-2500K rated at 95W. I constantly run Handbrake and play games, I do not have any over heating issues!-Cons: The product was delayed in its shipping. However, Amazon did refund the shipping fee and the product was in perfect condition upon arrival.Great product so far!
