Skinnee: A few thoughts...

First off, that test looks to have been a PITA. That said, how much full-load cure time did the MX-2 on the CPU and GPUs have prior to running the tests (thinking back to Vapor's experiments in charting TIM's thermal characteristics)? I didn't see that information in your methodology section (you mentioned no mount changes, but that was it). Also, looking at the averaged data from the CPU and GPU DTS, I'd wager all of the results (aside from the Fluid XP Nanofluid) fall within or pretty close to the margin of error--a heat source and sensor equipment that wasn't live computer components may have been a better choice....then again, it could also complicate things further.

...bah, I'm tired... I think I'll just shut up and go fix my car.
