In a PM to me you once mentioned that you weren't sure about the accuracy of AMD CPU's internal sensor. Has anything lifted your concern about that?

You could also test the IX vs a known paste on the AMD setup and then test all the other pastes on the i7 930; I think a lot of people would be happy if you were to do the testing on an i7 - I personally would be more than happy to donate the money for the i7 IX kits if that's all that's keeping you from testing on the i7 Seems like the least one can do considering all the awesome testing you've performed and are still performing...

As far as the Liquid Metal stuff altering the block/heatspreaders surface, I think this can be shown to be the case/not be the case by re-testing a paste that you tested before the Liquid Metal stuff.
