2 pumps together or seperate?
Ok Ive read up on some systems with 2 inline pumps and they all had the pumps connected to each other, seeings how Im about to hookup my second radiator I was curious if it would be fine to run the pumps seperately? I plan on running them on the same line just not right next to each other. There will be about 3 foot of tubing between them, I just wonder if this will cause any issues with the second pump, im sure it will work a bit more then the first pump but then again it will be pushing water back into the first pumpm, I just cant do the math right now so a second or third opinion would help me alot.
BTW this is on 2 Aqua Via 1300 pumps, which run 370gph @ 6'.

Put the pumps in parallel, that will give you the highest flow rate.
Q = AV Area (2 tubes join to one) goes in half, V (to keep Q constant) doubles. But, you must consider loses in internal friction, ect. It called the law of diminishing returns.

Ive got both pumps and both rads up and running, I actualy get more consistant temps with 1 pump running then with 2 pumps, but Ive dropped my idle and load temps by 8c with 1 pump, I* get better flow with both running but my temps creep up 1-2c. I was having some kink issues last night so I got some new tubing today and re plumbed my system for the 5th time. Hopefully its all done now for awhile.

If you run two pumps, don't run them next to each other. I would run them inline, but not next to eachother either. Hve one pump right after the radiator, then run all your tubes to your CPU and or GPU and other stuff. Then put the other pump between your heat blocks and the radiator. Running two pumps really does not help cool your PC much, it runs the fluid through the radiator too fast to cool itself. Liquid cooled motorcycles have a problem with fast pumps, you know what they do? They trim the fans in the impeller to make it pump slower. Just a thought.
