If I run 2 should they be back to back with the rads or run one near the MB?
I'm going with a test bench setup to ease access to components. It will make thing alot simpler as I will no longer need power switch or fan controller etc.
I'd guess that the 655 could hack it, the easiest way is to try it and see- if you wind up wanting a dual top let me know
I think it should be fine, it has (if memory serves) ~10' of head pressure, so you should still have good flow at the top. If you find that flowrates are low or you decide to add more restriction to the loop you may want the second pump, but I don't know that you'll have a problem. As I said though, let me know if you want my dual top, I'm considering upgrading to one of those Koolance 450x2's
