hi I’m planning to do a whole room watercooling system. 8 systems alle with 1080TIs and different i7 cpus, I already have water blocks for 4 of the 1080ti EK ftw3 blocks that I plan to use. I’ll like to mount a radiator on the outside of the house. I would prefer one or more car radiator for price and size. I’ll like to run it passively so I don’t have to use any fans, or only use fans on hot days. Radiators will be in shade all day. I get outside temperatures from -15 to +35 Celsius so I would use something with antifreeze. Everything should be able to run at the same time and run 24/7. First problem I see is if I use car radiator is they are mostly all aluminum. The blocks are Nikkel / copper. Also. A normal pump like the one I already have EK-XTOP Revo Dual D5 PWM Serial - (incl. 2x pump) be enough? Thinking I might go with something not normally used in watercooling. All PCs should be able to disconnect individual while all others run. So i will make everything with quick release coblings. This has 2 objectives. 1. Move the heat outside the room get very hot even with only 5 pcs I got running now. 2. Remove the noice from the room. Any thoughts, ideers and help is apriciated.
