I pmd RJ in regards, but I am curious as to what the average results are for people. It seems hard to find info on a dual 360MM rad setup with a gpu block/cpu block paired. I hear the gpu runs cool but the CPU gets warm. I was originally just going to loop my FE card with the EK block and an XD5 Corsair pump/reservoir and a 360MM rad. If a 12900K in the loop is viable I will do it, but I want to know what the average vram/gpu core temps are in this loop with a 3090/3080 TI. So I am thinking 2x 360MM rads paired with the XD5.

What exactly do you want to know? I'm running dual 360mm rads in my build. With my daily driver settings CPU runs at about 50-60C while gaming and about 70C full load at 5Ghz P core, 4Ghz E core. The RTX 3080 Ti tops out at 60C load in games at 2050Mhz core and 20Ghz memory. VRM gets to about 60C and memory roughly the same 60C. 

Basically what I was wondering is if a dual 360MM rad with the XD5 would be enough to tame a 3080 TI and a 12900K under overclock settings. I have heard the 12900K produces wild heat into the loop. Idk judging from you are telling me, it would seem its definitely viable. 60C vram is a lot better than the stock 3080 TI FE pads at 90c.

dual 360mm rads will definitely be enough to cool that. 

I agree. 

Okay I got my loop together and the temps are not bad at all. I lowered my CPU to a 5.0/4.0 because I wanted to drop my vcore by almost 1v. CPU averages about 60C with spikes to 70, GPU is at 61 core 64 Vram at 2860x1620 (new 4k DLDSR equiv) but the coolant temp is averaging at about 40-41C under game load. Thats also the GPU dumping 400W into the loop as well as 2100 on the core +800 Vram. My question is, what is the acceptable temps on the coolant loop itself? I have my 6x noctua's running at 1400 RPM and intake fans running at 1250 on the side of the Lian Li 011. Is this good or is that coolant temp too high? It is a very hot loop tbh.

60C is about as hot as you want the coolant temp for the pump and the seals. You are a very long way from there so I doubt you'll get there.
