CPU Core voltage high

[capitate]

I don't know why, but my cpu core voltage is at 1.66v according to Everest ultimate & CPU-Z. I bought this PC from a big box store a couple years ago, so I've never overclocked, nor do I know how to. The only thing I did recently was install Windows 7 64bit. (Tried reinstalling 32bit and it was the same.) I can't say Windows 7 caused it, as I've never checked these senors before; so I don't know if the voltage has always been like this.

I don't know if I should be worried??... my system seems stable atm.

I can almost guarantee you that is wrong judging by your idle CPU temps. Check your BIOS and see what it says in there.
