Question AIO for Threadripper 3900x series

[DomoDomo]

Greetings friends. I have scoured the internet and cannot find an answer for my issue. I currently have a thread ripper 3970x and a Noctua cooler with dual 140MM fans. I still hit 85 degrees during daily 3D rendering and 89 degrees during Cinebench. I idle at around 45-50 degrees peak summer. I have dual GPUs in my system. An Rtx 3090 and an Rtx 3070TI. would I see any benefits from upgrading to the ASUS Ryujin 360 AIO? Would love to see some benchmarks but it seems no one is liquid cooling a third gen Threadripper?
Thank you.

Yes. That’s the one with the dual fan config.

Well, it's not hitting the throttle limit, which is 95C, so things are still in the green.
Found the cpu specs here: https://www.amd.com/en/support/cpu/...ipper-processors/amd-ryzen-threadripper-3970x
If the case ambient temperature was lower, the max operating temperature would follow with it. Gonna be hard to do that if the 3090 and 3070Ti are dumping their waste heat inside the PC.

The Ryujin may not change much.
1)There don't appear to be any models with the rectangular copper plate, which makes full coverage on TR cpus. What will happen is that the CCXs at the far end will run warmer, counteracting the reports from the CCXs towards the center. Round plates have the worst coverage, and squared ones are in the middle.

2)AIO installation. There's this thing where the radiators apparently MUST be installed in the roof of the case, exhausting out the top.
The downside to that, is the case ambient being the main air source. Sure, the temperature spikes will be lower and less frequent vs air coolers, but in the right conditions, an AIO can reach the same maximum - it just takes longer.


If you must have an AIO, ones that have the rectangular plate would be ideal - options are very limited though.
Alphacool Eisbaer Pro series
Cooler Master ML360 RGB TR4 Edition(might not be available anymore)
If neither is available, then a unit with a squared plate - no guarantee it'll be an improvement over the current cooler due to what I mentioned earlier about the outer & inner CCX temperatures.

@Phaaze88 - Thank you so much for your response and help on this. My other option I was considering was to remove the 3070. I DEFINTELY do not want to buy and install an AIO if there’s a chance my heating might not improve. I have an phanteks enthoo full tower case with 6 case fans and a top mount area so could fit the AIO but all signs seems to point to my having a solid cooling solution and am just needing to make other adjustments if I need lower temps.

Yep. 👍
