I thought I would post some raw image results from overclock.net along with thermals. Nice clean prints. The 8A was a before a "washer mod" and 8B was after the "washer mod"

The increase in performance matches nicely with the increased contact and pressure (actually is as good as a couple of the better ones I have on file)

It's a nice illustration which you people already know and reinforces probably the most recommended forum troubleshooting solution to cpu thermal problems - Lap and tighten/balance the sink.

Thanks tkl.hui for the extra effort, much appreciated
