Originally Posted by rpm666 I vote parallel. I'll be testing out the parallel radiators here next weekend. Splitting the loop into A and B, each A and B hits a pump, goes into Rad A and Rad B, then join together just before hitting the CPU. Right now heat is not an issue since I mounted a triple rad outside - idle 10C load 32C (different project). In the weeks to come I want to have both my main rigs on one large loop with 3 rads, 4 pumps, and a lotta blocks with many things in parallel.

Originally Posted by hometoast No first hand knowledge, but I would expect a laminar flow to have higher temps over a flow with a bit of turbulence. Unless I don't understand the term laminar, it (the coolant) would, only be in contact with the radiator on the outside of the tube while there remains some water traveling in the middle. The tube of water would cool less the closer to the center of the radiator tube. I thought it had to do with the "positioning" of the mass of water throughout the path. |
@Ira-k... I was going to suggest instead of a bunch of Y fittings, use existing components... GPU full cover blocks are perfect for this.. you can use one inlet that will feed both blocks when set up right, then have both blocks with an outlet. Effectively producing two outlets from existing hardware. those outlets go to individual rads... Then the rads go back to a reservoir that has two inlets.... there you go! ZERO Y-adapters! |
