Is it possible that you were a little cheap with the paste since you knew it was going to be coming apart next week?

It will be interesting to run the same test when you have a water block installed and see if anything changes. I've seen a lot of screen shots and yours just looked a little unusual.

Your friend has core0 sticking at 65 away from TJMax and core1 might be stuck as well at 66 from TJMax. The test is very conclusive for core0 but not conclusive for core1. You would need to test again with colder water to try to force the CPU to a cooler temperature and see if core1 can reach more than 66 away from TJMax. You could also redo the test with less MHz and core voltage when trying to get some lower CPU temperatures. Less core voltage is the most important one.
