whatever setup you decide to use just keep in mind that you dont want too much water flow, I you do get to much then the water will be moving too fast to absorb the maximum amount of heat that it can, this is where you get to do lots of testing with different flow rates,to adjust flow just put a valve somwhere after the pump or right before the block. I am running my rio600 pump moded so it sits outside the res. then rad. and the valve to the block and back to the pump. Works pretty good right now, still havent problems getting accurate readings with my probe, think it may be dead or bad,oh yeah i got a pelt too.
hope this helps some.....if any LOL
