haha...if my experiment fails .. at least I won't be alone right BrianW.
Just got my 2nd pump yesterday...still waiting for my blocks though. Maybe if u wait a little longer, I could tell u if our little theory works or not

That might help u save some dough.
Do remember, tubing does matter for high flow rates. There was a tubing recommendation graph that I say somewhere b4. I think it went somewhere along the lines of 1000lph 1/2" tubing 2000lph 3/4" tubing. Thus, I might give my CPU block a 16/22mm tubing straight from the pump. Once the water goes inside the block, there is nothing much I can do anymore.....:shrug:
