Guys, I like versatility in my rig, I want to turn it on and play BF1 then bench a bit etc when I feel like it so I have an idea. Its a bit crazy and I know there will be haters but hear me out and tell me what you think. I like water cooling but I want to get temps down further for benching without making it a trailer sailor (car term) so what if I build a special heat exchanger that is unused most of the time and remains dormant, but when I want to push the boundaries I can drop some dry ice in and suck some more heat out of my loop without going too cold (without insulating). What do you think? I like chillers but I dont want the condensation issues or noise. I like phase but they cant cope with the heat loads of modern cpus (not even looking at cascade). So is my little dice pot a good idea? Will it work? Any other ideas that will give a similar result? The exchanger could be a 120 radiator inside a metal container/pot/tray/box or even a proper dice pot contacting onto an extra cpu block in the loop. I could even use something like the old "cool can" they used to use on carby cars to keep fuel temps down (simple coiled pipe inside a metal bucket like container). If I could generate enough cooling using a single stage phase rig I would consider that too but they wont have the capacity I need (particularly if gpu is in the loop). Or I could test it on a gpu loop first and see if it works. Any input would be great.
