Thanks for the input Matm347. It's more my compulsion to OC anything with wires attached than a lack of familiarity with WC systems. After years of building gaming PC's with WC systems/kits, I've just currently made the evolutionary jump to water myself. So, maximum performance has suddenly become a more crucial criteria to the n'th°. Which puts me on the tweak quest for afordable near subzero temp solutions.

Your reminder of water a temp sensor was an obvious point overlooked, cudos. In spite of my future proof builds, finance/technology mandate prescision tuned WC to keep afloat. At this stage the thrill of the challenge leaves me with an exuberant thirst for knowlege.......quite like Johnny 5.....Input, need more Input. I do enjoy this whole alienated Alien scenario to the extreme though larger data base is a priority!

Well, thanks again, and I'm off to purchase more 5052-H31 aluminum stock & a '77 Pontiac dual heater core.
