Inexpensive Air Cooler That Stuns! I bought this cooler for my build which was compromised of parts generating bang for the buck. I originally bought a liquid cooler for my system but at the last minute had a change of heart. I had always read great things about Noctua brand coolers therefore I gave this little guy a shot.The processor purchased for the system is a Intel Core i5-9400F, and it came with the standard garbage cooler. When you turn a system on with that stock cooler, it sounds like a swarm of angry bees trying to raid your living quarters! With the Noctua cooler...it's like its not even there. The system turns on almost without a peep. I may not have the temperature readouts or system information readouts to bear out my statement, but I'm really impressed with this cooler.My only complaint truly is the brown color. Mounting the screws on the underbelly maybe a pain, but also consider most cases nowadays allow you direct access to that part of the system without much hassle. For me installation was easy on a Rosewill Challenger S case.For roughly $10 or so more than a Hyper 212 cooler, this is truly among the elite of air coolers! 5I'm very happy with this CPU cooler as my Pfsense firewall is ... I use this cooler as part of a Pfsense firewall setup running an Intel Core i3 Processor in a Mini ITX industrial case. This cooler is absolutely silent. When the system is under load, which is rare, the cooler makes a barely imperceptible hissing noise.I'm very happy with this CPU cooler as my Pfsense firewall is naturally always on. The CPU temperature stays consistent at 28 Celsius. I attribute the consistent temps to the function of this cooler. I highly recommend. 5A fantastic S4 Mini compatible cooler Fantastic, luxurious, silent, and icy cool. I test dozens of coolers under 40mm for my system integration gigs and custom SFF system, like the NFC-Systems S4 Mini. This is the best bi-directional cooler under 45mm that I have seen by a far margin. It is expensive, but worth it. The fan is very quiet and I am glad because many of my systems are built for small radio and television studios and are unisolated.This works beautifully in the NFC-Systems S4 Mini and I highly recommend it. 5Perfect For It's Intended Use When using this thing for the appropriate CPU and reasons (i.e. non-overlocked CPU's under 65W TDP, intended for low noise, provide better cooling than OEM coolers, etc.), this thing is perfect. I have no doubt this thing would keep an i3 and probably an i5 super cool without even breaking a sweat. i7's and anything ending in a "k" is another story.I attempted to use this with an i7-7700k (not overclocked). The manufacturer's website makes it pretty clear that this thing is intended for CPU's with a TDP of 65W or lower, and the i7-7700k has a TDP of 95W. This did not keep my CPU cool, and the CPU ended up thermal throttling with any sort of stress test in less than a minute.Reasons I'd suggest this cooler:- Low-profile builds- If your intent is to reduce noise levels- Provide better cooling than the stock Intel cooler that comes with most CPU's- If you have the Noctua pooh-brown color theme going on with your components 3Okay I replaced my stock Intel fan for i7-8700 with NH-L9i. This is my first Noctua product, and I like it.Even though I had to open my other side panel to replace the fan, it was not that hard. Also, since this fan is low-profile, I still have a lot of room. The package contains its own thermal paste and they are pretty good.I have no problem with its noise level and I did not use low-noise adapter.The performance wise, however, not perfect. On idle, it keeps all 6 cores below 30 C and my lowest is 24. But when I use Adobe Premier Pro or After Effect, especially during the rendering, it goes up to 90 C which might cause some issues. General gaming, it keeps between 50~55 C.I think this is okay fan without any heavy work. I also purchased a 120mm case fan from Noctua, because I think they are reliable. 4Awesome for ITX builds Pros: Doesn't touch my RAM The heatsink looks very premium Works with my Intel Core i5 3570K Comes with a nice little case badge The heatsink has an amazing build quality I get better results with the included NT-H1 thermal paste than with Arctic Silver 5Cons: The NF-A9x14 fan died on me and Noctua had to send me a replacement The mounting solution is kind of annoying since you have to remove the whole motherboard in order to get to the screws at the bottom of the motherboard 4Excited when ordered - Disappointed after installation I built a mini ITX system in an In Win Chopin case (which is very nice for this purpose). I was using the Stock intel fan for an i5 8400 CPU and was getting idle temps at about 34C. I read all of the great reviews about the Noctua NH-L9i and upon opening the box, I can see the quality and attention to detail. I installed it and was getting 36/37C idle temps. I thought, that can't be right, maybe I didn't install it correctly? So after 3 attempts at installing this with the Noctua Thermal compound, I am still getting 36/37C idle temperature. Now, the one thing I will say is. It is near Silent, except when I Ran Cinebench CPU test. Then the temps went up to 77C hitting 80C at one point. The temps come down quickly after the test, so I guess that is good too. I am disappointed. I was hoping to reduce my idle temps by a couple/few degrees and reduce the load temps too. I hope this helps someone. I really did want to like this. I may end up keeping it if I can't find a better cooler in the next day or two. If I do keep it is is because of how quiet it is and it is about as good as the stock collar from a temp perspective. 2This is the real deal. Struggled to pay such a premium, but it was worth it. Max temps down 10 degrees average. And despite this, the loudness of the CPU fan is dramatically reduced, almost inaudible now, vs stock cooling, which was previously the loudest fan of all in my case + my 4 HDD hard drive bay sitting next to it. I'm using this with an i7-8700 3.2GHz 6-Core Processor in a Cooler Master - Elite 130 Mini ITX Tower Case. This setup sits on my desk, and I have a projector in the same room for the occasional movie (streamed using Plex from the same PC), and so my PC needs to be quiet.Photos included. Check the Max. tump column in the middle for before n after.Can't believe it's silent and cooler at the same time! 5Comparison vs a Cryorig C7 in SFF If you're coming from a Cryorig C7 or even considering it in a super ultra tiny PC build: PICK THE NOCTUA!!I recently built my Dr Zaber Sentry, a 7L micro gaming PC build. It houses up to 47mm CPU fans, and the Cryorig was rated for a higher TDP, and I had an i7, so I bought the Cryorig. Turns out the Cryorig is loud, like really really loud, spinning up very very audibly under any load. Admittedly, I wanted to keep the Sentry on my desk, which might be abnormal, but I spent $200 Indiegogo'ing a case because I like how it looks on my desk; what can I say. It was audible over low-volume headphone game audio, even. So I tried this out as well as delidding my processor, and the difference is significant. I can't say clearly how much was the delidding and how much was the Noctua, but I will say this: manually adjusting fan speed to 100%, the Noctua sounds about 25% quieter, but the big deal here is the optional in-line resistor.In building a super-small case, you discover that your BIOS wants to keep your system at temperatures designed around a big open airy case. This just isn't feasible for a case like the Sentry, so I wanted there to be a way to say "hey, the Kaby Lakes run super hot anyway, and my case is small; chill about the temperatures". Connecting the included "quiet mode adapter" essentially does just this, by lowering all voltages running to the fan.This is a great product and is very silent under normal conditions. It's also worth mentioning that the fan is interchangeable for up to a full height fan, whereas the Cryorig's is not. 5High quality, extremely quiet. Highly recommended. I bought this for the Intel Pentium G4600 which comes with a pretty loud and cheap fan. I should know better by now, but first tried to buy a cheap (< $20 heatsink and fan). I had to send that back. The Noctua (low-profile) CPU cooler is a little pricey, but you get high quality extremely quiet cooling for your money. Installation is a tiny bit of hassle, since it requires access to the back of the motherboard, but once installed and you turn on your PC and listen to the lack of sound, you will be happy you spent the time and money. Remember to go into the BIOS setting and manually set the fan speeds to very low, or choose a "Silent" profile. Check the fan speed with something like HWInfo64. Then install the included adapter cable to make the fan run even slower. I have mine set to 400 RPM or so at 30C CPU temperature. No matter the fan speed though, it's extremely quiet, but of course, at > 1500 RPM there will be a slight whisper from the fan blades. 5
