I used an old water jug as a glorified heat sponge to soak the heat for the few seconds it needs to be at the frequency to validate. On the return, a HUMVEE heater core takes the edge off of the incoming water. Also, my only spare water block was for AM3 so some creative liberties were taken with the mounting mechanism. Unfortunately, the bclk moved between the screenshot and validation so they don't line up, but you can see it change in the video if anyone asks.
