I don't monitor the temperature, but I do hear the CPU fan speed ramping up and down when I'm building ports like this. Even though I'm pretty much keeping one core busy the whole time, the temperature must drop enough at times to let the fan speed drop. I can run math/mprime on this machine for a while to see if anything shows up. I also have a very similar machine (same motherboard but different CPU) that I can move the drive over to and test.
