OK I am in the clear. The temperatures were 5C lower than my test run last night because when I pulled out the CPU and changed Goop application I left CPU at 11X multiplier. So it isn't running at the same speed. I'll bump the speed back up tonight (don't think there will be a dramatic difference in settling over 12 hours between 12.5x175 and 11x175 at same voltage) and run tests again.
The heatsink goes on and off much better after a couple of remounts; this doesn't bode well for the reproducibility of the early data sets.
The Vantec Tornado even at 5% PWM is louder than the HDDs. The full power Stealth is quieter than the HDD so that's the noise I hear. Outside case noise levels would imply that I have doors on the case. Can't easily do that and still mount the Digitec air probe.
