I'm inclined to give this a whirl, but from reading the review and comments I have a worry:

When the reflow process is done and the whole thing is settled, powering back up your water loop.. wouldn't running a high load that makes cores reach 90 degrees start the reflow process once more? It seems a bit 'dangerous' when my mobo is vertically during normal operation. I'm sorta weary of unwanted reflows whenever I run stability tests during OC that may push cores to a 90+ degrees.
