So I recently, in preparation for an upgrade to a 9950X3D, decided to put a full open loop back in my system, with the CPU only to start - going from an EK Nucleus AIO (which is one of the best 360mm AIOs there is in terms of temps).
I knew that the 7800X3D runs hot because of a combination of bad core-to-IHS heat transfer, and the 3D VCache being on top of the CCD - instead of underneath like the 9000 series are/will be. Either I got a really good sample, or the EK AIO was amazing, because I've looked at other people's load temps under a full loop with quality blocks, and they're talking about 36-42C idles with loads ranging from mid 70s to the mid 80s... My temps with the AIO topped out around 79C most of the time, both with a heavy curve optimizer "OC", and recently with a 104MHz ECLK OC, which results in ~5000-5025MHz all core boost under R23 load, and 5225MHz low/single core boost.
I assembled the loop, put it on, ran some tests, and my temps are... Only slightly better? I'll post some screenshots when I get home. But it's only about 3-4C better. Admittedly my cpu block is a cheap one, and apparently radiator volume makes no difference, I hooked up my old 480mm x 60mm rad to the loop, with push pull fans, doesn't seem to make any difference on fan speed so I set them to max out where they're barely audible.
What temps are you seeing & what cooling are you using?
