.pdf says 4.5-5.5 for VCC; no data for effect of VCC on temperature in specs but every other parameter is graphed.

I had some serious problems with that PSU though and AMD CPUs will stress the 5V rail. I guess a PC PSU that allows you to dial up the 5V (as measured by Vin on Maxim) would be the way to go if you wanted to monitor VCore at the same time. Thermaltaco sells some with potentiometers in a bay drive for adjusting power. Alas! If I only had a grothmeter (and a way to convert output current to a voltage I could read with maxim Vin...
