I was going to mill my own waterblock out of solid copper, and put the old 8045 on top of the waterblock in case the pump breaks or something, but then I got thinking. If I'm already making my own waterblock, why not make it directly in to the 8045! I'll just mill out a maze on the bottom and attach a copper plate directly to the Alpha. This would give me hopefully even better cooling through the giant fins, and a backup HSF if the pump fails. I'll just hook up a sensor that turns my HSF on when the pump goes off.
