Mini Threadripper Cooler: NH-U9 TR4-SP3 by Noctua

Pretty sure you are supposed to use the whole tube of thermal paste for the CPU. Ya know, to help get rid of any possible trapped bubbles

[@STS]

These Threadrippers require quite a bit of paste, maybe time to buy some stock in Noctua :)

I use the same cooler with my 1950X. Mine is in a rosewill 4U rack chassis

Hi rdsii64! That's awesome! I had wanted a 1950x but couldn't pass up the deal I got on this 1920x and A stock x399m motherboard. This is the smallest Noctua option for TR4 but since it fits in a standard 4u it's a winner for us. How well is it cooling your 1950x? Is this your virtualization / homelab server?

How much TDP does this NOCTUA model have ?

[@STS]

I'm not sure this cooler has a traditional TDP rating. It is for the first and second gen Threadripper CPUs. This cooler is for people using threadripper either in a smaller SFF case or a 4U server. What CPU do you have?

[@pedrohyago1735]

@@STS I will use the EPYC 7763 and I saw that this heat sink will not support the 280W of the CPU. I found another heat sink, the ARTIC FREEZER 4U SP3, it has 300W of maximum TDP, I just have to see if it will fit in a 4U chassis. LoL

I do not believe Noctua rates coolers in the traditional "TDP" sense, you can see the article here: noctua.at/en/noctua-standardised-performance-rating. I have both the Noctua U9 and Arctic 4U SP3 for my Threadripper 1920x. The difference in cooling ability is massive, massive. The U9 will fit any standard 4U chassis as it is short. The Arctic 4U may or may not fit your chassis, the tolerances are that close. Craft Computing was not able to fit this cooler in the case he used. I was able to fit this cooler in my Rosewill RSV-L4500 and close the lid with no interference. The Arctic coolers cooling capacity is much greater than the U9, if it fits in your case, it is the best 4U SP3 cooler you can get before enterprise grade (very loud) or water-cooling.

Thoughts on running this with the NF-19x14 high speed fans? I have a 2950x setup, and my AIO is on its way out, but due to case/RAM clearance issues, I can't go NH-U12 or larger, so I'm thinking of going U9 with the slim fans, but I worry that they won't move enough air through the fins. How were the temps with the low noise adapter on the 25mm fans? The airflow there seems comparable to the slims, just with less static pressure.

Hi Chauntalei! The U9 TR4 is quite short, short enough to fit into a 4U server cade in fact, ~125-130mm depending on your motherboards memory spacing. The 19x14 fans push a little bit less air and don't create as much pressure so, if you don't need them, I would run the stock fans instead. The temps were great when running stock. I was able to finish my all core overclock with sub 75c temps on average at 3.7GHz. Im running this as a server so stability is more important than clockspeeds for me. If you have a confined space, this is a great cooler. The questions I have are what case are you running this rig in and do you overclock your 2950 currently?

[@5h4ck]

@@STS No overclocking, and I'm running in a Cougar MX331, which only has a max cooler height of 155mm. Coupled with 4 sticks of Vengeance RGB means that the 25mm fans on the U9 would need to be raised up a bit to clear, hence the idea to use the slim fans instead.

[@TheRealJoelKolb]

You don't have your fans placed squarely in the center of the fins which is not how the manual instructs that they should be mounted. I can see that you did this because of clearance issues with the heat spreaders on that G.Skill Ripjaws RAM. You've got those fans positioned about 13mm higher than they're supposed to be and as a result none of those fins are getting air blown directly on them by the included fans the way they are supposed to. It obviously works out fine for you but because of this your scores should come with an asterisk since they aren't a completely fair representation of this cooler's performance.

[@STS]

This point you bring up is somewhat fair but keep in mind, there are virtually no performance memory kits that do not have heatspeaders. The threadripper platform was designed as a high performance workstation platform meaning, high performance memory was intended to be used. This has been a complaint from every reviewer because virtually none of the customers will be able to run the fans in the correct way. I think I mentioned the fan positioning in the video. You could optionally choose to remove the heatspeaders but I believed it is unlikely anyone will. This is why I have tested the cooler in this configuration.
