NoctuaNH-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.

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!

These Noctua thermal solutions are so well designed. Now that I have used them I will never go back to the cheap substitutes. This model fits into my small chassis cools great and runs supper quiet.

This cooler Noctua NH-L9I came packaged with VIP Presentation. The quality was noticeable on first look when unpacking. This cooler was smaller than expected but does a better job than any stock coolers. I was indeed very surprised just looking at the photo online this appeared like a cheap cooler. It was far from cheap quality. The craftmanship and presentation is beyond 5 star.If anyone at Noctua is reading this the brown colored fan does NOT do this quality cooler any justice. It is outright ugly so my impression and alot of people on first look will judge this cooler by the way it looks. It is indeed a very nice cooler if you look pass the ugly brown color. If I was in charge at Noctua I don't care how cheap they're getting Brown PVC injection molds I would replace the ugly brown colored fans with something more mainstream such as black or any other pleasant looking color.I'm using this to cool an 8700k in a Dan Case A4SFX v.3 using a Gigabyte 370N ITX socket 1151 motherboard. It fits perfectly. Installation is incredibly simple. Just screw the cooler on from the backside of the motherboard. The fan is already mounted onto the heatsink so it makes setting up simple.

Bought around 2021, has lasted me so long and given me no issues. Thinking it's time for paste reapplication, so thought to review. It's as quiet as it can get, and while it looks ugly, you can buy the RGB rings that go over the fans. This goes right over my i7-4790k.
