Noctua NH-U14S TR4-SP3, Premium-Grade CPU Cooler for AMD sTRX4/TR4/SP3 (140mm, Brown)

Very easy to install. I didn't know until I got it that you can get one with a second fan. I'm ordering that for my computer as the Threadrippers runs even warmer than I thought it would. Make sure you have good airflow in the case! It works very well at stock speeds and maybe a mild overclock, but beyond that, unless you have a way to keep your computer room very cool, it will get warm. I tried the 3960x with a liquid cooler at first, but although it kept it below the throttling speed, it was getting quite warm. The standard water coolers just don't cover enough of the cpu to keep it cool. Putting it in was very easy. Cleared the memory on my Gigabyte Aorus Wifi Pro MB with no problem, but I only have four sticks of ram. If I had more, it would have hit the top of the sticks closest to the cpu and wouldn't fit. If you are planning on using more than four sticks, they had better be very low profile. Your MB may be different and have more spacing though. It cleared my video card which is in the first slot by at least 6 mm, although there is an adjustment to move it up to 6 mm higher up in the case if needed. Heatsink seems to be solid and very well made. It's tall, so check your clearance with the side of the case. I've got an old Cooler Master HAF 932 case and have four fans mounted on the side, and it still cleared with plenty of room. Even though it came with only one fan, it includes clips for a second one and a tube of thermal paste. It also comes with a short cable you can attach to the second fan to keep it at about 1200 RPM for quietness. I don't think the second fan will add that much extra noise as they are rather quiet fans and are 140 mm. They come with extra rubber isolation pads to keep the fan from vibrating against the cooler. All in all, a good product for a fair price, (considering what everything costs these days). Amazon shipping is also very quick, even without paying extra for faster shipping. I ordered it on a Wednesday evening, and it arrived on Friday about noon. I live near a large city, so your mileage may vary!

I really like the NH-U14S. It's very capable, but I'm not an overclocker and didn't expect it to cool beyond stock settings which are somewhere around 330W or so at the wall. That would put the CPU socket probably around 250W. I do NOT suggest the smaller version of this cooler. If you are going to air-cool a threadripper and choose Noctua, you want to get the U14S. A couple of notes on this cooler: The cooler partially blocks one DIMM slot, but its above the slot. Simply removing the fan (which takes 2 seconds) clears the slot for putting a DIMM in or taking it out, then the fan can be put back on and will be above the DIMM. This is a major plus. The cooler includes one fan, but also includes a strap for a second fan so you can boost heat extraction (and noise) by adding a second 140mm fan if you like. The fan is fairly quiet considering what its being asked to do. A lower-noise setup is possible if you use XFR2 + PPT settings to reduce the power envelope below stock. The cooler is designed for front-to-back airflow. Front-of-case fan-in, cooler pulls the air through to the back of the case, and a rear case fan to pull the air out. I recommend a front AND rear fan at a minimum, inline with the CPU socket. The cooler is fairly hefty and I do not recommend a vertical motherboard. Keep the motherboard flat if you use this cooler (and this is true for any bulky air cooler). If you need more cooling, intend to mount sideways (vertical motherboard), or need to fit the threadripper into a lower-profile case, consider a liquid cooling setup such as an Enermax. The advantage of using a liquid cooling setup is that you don't really have to worry about case airflow so much, whereas with an air-cooled setup you have to make sure that the front-to-back path is clear. The advantage of air-cooling is that it is extremely robust (no liquid to leak, no AIO pump, the fan is the only moving part). The disadvantage is that you will have non-uniform heat distribution on the motherboard. For example, the DIMMs on the exhaust side of the fan run considerably hotter than the DIMMs on the front-side, and same for the VRMs. So air-cooling is best when you aren't pushing the limits of the system, whereas liquid cooling is best if you are (or for the other reasons iterated). -Matt

The Noctua NH-U14S TR4-SP3 fits the ASUS Pro WS WRX80E-SAGE SE WIFI motherboard perfectly. I’m using it with an AMD Ryzen Threadripper PRO 3955WX, and it keeps the CPU nice and cool even under heavy load (main use cases include Game Servers, TrueNAS, and ProxMox for my homelab). Installation was straightforward, the build quality is top-notch, and the fan runs smoothly without excessive noise. It’s exactly what I expect from Noctua – reliable, effective cooling with no surprises. If you have a Threadripper PRO and want a cooler that just works, this is a great choice.

I have an AMD 2950x CPU and was having a great time with it. Had a well known liquid cooler that has the words "TR4 II 240" in it. It was ultra quiet and worked great. Great that is, until the pump failed at about 15 months in. It's under warranty, but, my PC was only useable for about 5 minutes at a time with no working cooler, and it left me stranded and so far they aren't being quick with my warranty ticket. So, I needed something to get me back in action and this was not only one of the more affordable options but also well-reviewed. I threw the Noctua cooler on and its been doing a fine job keeping my CPU in the ~40C range for a few hours. I haven't pushed the PC to its limits, but I think it will suffice. And, it's really not that noisy and should actually be a great cooler. Not sure what I'll do once the other one is replaced. It's tempting to just keep using this one, since it works so well. At least its an easy swap. It came with the mounts, some thermal grease, a wrench, parts for adding a 2nd fan if you wish, and everything needed to get it going. The ONLY downside I found so far was that if you leave the fan mounted in the default location, it hits my DRAM because it needs to be maybe 1/8" higher or so. So I was forced to attach the fan just slightly higher by 1/8" to 1/4" than centered on the cooler. Otherwise, it's great.

I needed another cooler while my Enermax AIO is in route to RMA department and will hopefully get replaced. I picked this up because the reviews (outside of Amazon) said it gets the job done even though it's an air cooler. I also have other Nactua fans in this rig and my other appliances around the house. They perform really well in general. Well, they were right. I'm getting lower temps with with this air cooler than I ever did with the enermax liquid AIO. Granted, the Enermax was apparently defective (thanks for not telling me via email, Enermax) and manufacture was replacing them for anyone who opened a case (Reddit for details). That said, even when the AIO was brand new, I never reached below 32 C. With this air cooler, I'm getting 29 at idle and it is very quite. I applied some load and even then, it never went over 43 C. Ambient temp in the room is around 73 - 74 but overall, I really do see a very significant difference in cooling performance. It's only running with the fan that came with it too. This cooler can be configured in a push/pull setup to improve performance but at the moment, I don't think that's necessary. So it's very likely that even if I get a replacement AIO from enermax that I will continue to use this air cooler. It's quite, performs really well, easy to install, price is good and Nactua will throw in a spiffy case badge too. I highly recommend it if you are running AMD 1900x.
