Voltage goes up if the chip turbos right?

Voltage is scaled to frequency, so, yes it does go up in turbo mode, but it also goes up as the chip moves from its idle to loaded speed-step states.

So, disabling turbo specifically on the 5960x will keep it between 1200 and 3000 MHz but it will vary in between there unless you also disable speed-step.

You can set whatever multiplier you like as well from 12 to 29 if you want it to run slower than stock. You can also set manual mode on the voltage as well if you don't want that fluctuating, but it will need to be set at the voltage required for the highest frequency you allow in your config (see above).

p.s. as the first reply mentioned, if I saw 67 on boot up with any decent cooling arrangement, I'd be looking for installation issues. It just doesn't get that hot until you push it. I had an AIO fail on one setup so the pump wasn't running at all. I could get into and remain in the BIOS never breaking 40C with nothing but the copper mass and static fluid in the AIO (because the pump was dead) there to remove heat.
