I successfully unlocked the 4th core on my X3 720 and overclocked the CPU to 3.6ghz. Voltage stays the same with the 4th core unlocked, at 1.41v, but I noticed that the CPU temp went up about 4c from 50c to 54c. I guess this makes sense because now I have four heat producing cores instead of just three.
Note that the CPU temp is the one from the motherboard, not the core temp. With 4th core unlocked, I can no longer monitor the core temp, which tends to be about 5c lower than the CPU temp reported by the mobo. So I estimate the core temp to be 49c unlocked, versus 44c with 3-cores.
I ran some benchmark and used the computer with 4-cores for a few days and it seems that having an extra core doesn't do anything. There is no noticeable speedup whether in office tasks or in video games. So is it still worth it to keep the 4th core enabled despite the higher CPU temp?
