loop questions (2 CPUs) - Page 2

post #11 of 15
Like Charlie and Fat Italian Stallion said rads dont add much restriction to the loop. I was running 2 cpu's, 3 gpu's and 3 rads with 1 355 pump no problem. I added a second one just for redundancy but is not needed.

two pumps w/ dual top seems like a good idea.
I'm running cpu, mobo, 2x gpu's, and 3 rads off a single d5 but your going to be running more along with larger capacity rads.

Make sure to post some pics when your building/ done. Sounds beastly

This is all interesting. I fear doing a y-split type of thing because my instinct tells me that the flow of one of the splits will slow or stop. I need to research that more. I have been reading about 2 pumps, but my understanding was that it wouldn't make much difference. I am drawing up different tubing serums right now to try and decide what makes most sense for me

the flow will only slow or stop if one side of the loop has more restriction than the other. If you keep it equal you won't have any problems

I wouldn't bother with the split for the CPUs, they don't really change the water temperature by more than 0.8C.

A 1 GPM (typical flow rate) it takes 260W of heat to raise the water by a single degree. A 150W CPU will thus only raise the temperature by around 0.58C, a very small amount. This issue is more prevalent when you are stacking multiple 300W GPUs on top of each other in tri and quad SLI configurations.
