Here are the cliff notes: A couple years ago I saw a local craigslist ad for some "water cooling equipment", I knew it was all junk and I didn't really want any of it, but the seller had a peltier and I said "can I buy a peltier for $5 from you?" and he said "you can have the whole lot for $5". That is how I ended up with 5 peltiers (unknown wattage/specs), 2 120mm radiators, and 2 12V DC pumps for $5.I didn't even want 9/10 items but here it is occupying space in my basement. Fast foward to today, I purchased a 220W TDP AMD space heater a couple weeks ago. Next I ordered a Noctua DH-14 cooler for this CPU, and my CPU didn't melt when it idled in the BIOS. I haven't yet installed an OS and tried any tests like video encoding or prime95 since I'm still kinda nervous about the idea of having X many pounds of gigantic Noctua CPU cooler strapped to my motherboard. I'm nervous about the stress of the weight of this cooler hanging off the side of my board and the impractical way I can think of to relieve the strain is to douse this CPU in water. I know have a "ZKSI" brand DC30A-1230 pump, an AGPtek radiator, some vinyl tubing from Home Depot and a $2 aluminum block from Ali-Express.I do not have any sort of official radiator, and I am attempting water cooling the cheapest way possible. Things are going to go wrong. That said, is it 100% necessary to include some sort of reservoir in this cooling setup? I'm totally with buying a cheap reservoir, but I think AIO coolers lack reservoirs so surely I can test this setup without a reservoir? I do not believe my low budget parts will sufficiently cool this CPU, nor do I expect to not have leaks, but thus far I have invested ~$10 in all of my water cooling parts and I'm hoping to have a proof of concept that I can upgrade in the future. Just how terrible of an idea is this? Actually, I'm not sure I want to think about that. Is a reservoir 100% necessary or how can I get away without using one?
