Amazon.com: Customer reviews: Noctua NH-U9 TR4-SP3, Premium CPU Cooler for AMD sTRX4/TR4/SP3 (92mm, Brown)

Great cooler, bought the smallest one to fit in a 4u chassis with an sp3 and epyc and it’s noctua so of course it’s quiet, moves some good air and cool. 32 core epyc 7002 at 2.9ghz I don’t run it hard all the time but I have yet to get a thermal throttle. It fits in a 4 u chassis but also fits in my ancient nzxt m59 with a supermicro h11. Worked well til the server rack got in. Anyway good quality, solid design, and fits how it should!

Amazing little cooler.

Use this in a 4U server. The cooler is mounted on a 1920X (12c/24t). Tested with prime95 @ 100% load never tipped over 65c. Really impressed with the performance and how quiet the fans operate even under full power. Obviously your mileage will very depending on your cases airflow. The craftsmanship of these coolers is second to none and the mounting brackets are the easiest I’ve used by far. Only thing I’d like to add is that seeing these brown fans is like an insurance policy that your not going to have any troubles for a very long time. So don’t be thrown by the color, it’s a brown beacon of light in a ocean of terrible black/RGB fans.

Good for TR4

My liquid cooler died and I needed a cooler fast. Amazon delivered this Noctua NH-U9 fast within 36 hours. There aren't a whole lot of TR4 cooling solutions out these days. I guess it's an old chip. I am using this on my 1920x. I had to remove one stick of my vengeance RAM to fit it. Keeps the cpu hotspot at 65 under load, Celsius. Under sustained load it may be a bit higher. My liquid cooler wasn't running great after it's first year the temps got higher. Think the microfins got clogged. This Noctua NH-U9 arrived fast, came with a y fan splitter, and paste and even a tool to screw the heatsink on. The temps are about what you would expect for it's size, won't have to replace this cooler for a long while though.

My main goal was looking for a cheap and great performing cooler that would fit a Rosewill rackmount case for my Threadripper system that I use to run VMware Hypervisor. I was using an Intel based motherboard which died, so I replaced it with what I had on hand, which was a threadripper based motherboard. I had a height requirement, but I also wanted to best performing air-cooler. This has been performing like a champ for months!!

Smallest Treadripper Air Cooler

Reviewed in the United States on March 8, 2019

So this is the smallest Threadripper air cooler out there at 125mm in height and really it is meant for server racks or SFF builds that just don't have the height clearance. If your case has substantially clearance I would recommend skipping the U9 and U12 all together and just go with the U14 TR version since all of these coolers are so closely priced together but the U14 is the only chip that offers very good cooling with real overclocking potential. With this said the U9 TR4 is rated at 180W TDP, so yes it can handle a 1920X-2920X to a 1950X-2950X but not the WX series chips. The cooler is beautifully packaged and comes with all sorts of cables, a long screw driver, and thermal paste. The 92mm fans aren't as quiet as I thought they would be at full load but still aren't obnoxious. Mounting was super easy but it should be noted that this cooler does require low profile RAM or the fans interfere with the RAM. You can slide up fans up the heat sink but I am not sure how that effects cooling. I have the NH U9 TR4 in a mATX Sliger Cerberus 18.5L case with 6 case fans. The two most important case fans for my build are the top mounted 120 slim exhaust fan and the most important one is the side bracket mounted fan that intakes air and it sits right above the cooler barley not touching it. The side bracket fan lowered Idle temps from 39C to 34C and allowed me to run my previous Ryzen Master settings that I had with an Asetek 240mm AIO. When stress tested with CPUZ I am getting 67.75C which just barley is under the 68C throttling limit. Overall this is the only TR4 air cooler that fits into my case and by no means is it a bad one, but it does takes a bunch of fans to keep it properly cooled

It is very expensive, a very good product, but expensive.

Easy to install.
Compact, good for mounting but I prefer a larger heat spreader for optimum dissipation.
There is another model, that is no compatible with my processor but could do a better job.

It works well, but it's pointed the wrong way.

It works well, but the fans can only point up or down. I had to drill a hole in the top of my PC case to ensure better airflow. The installation was easy and the fan is really quiet even at Max speed without the low noise adapter. I need to replace the case and cooler later on. My CPU will get too hot if I start CPU encoding.
