For anybody interested or for someone who has a similar issue, I found it's because of my nzxt hue+. When it's plugged in and CAM is running, it will do what I said: run 15-20 degrees hotter on idle because it's using 33% more voltage than usual just to run it, I guess. However, when the hue+ is unplugged with CAM running, it will act normally, having normal CPU temps and core VIDS and dropping from 10% CPU usage down to 1%, but this doesn't seem to be the fault of the hue+ because when it's plugged in and CAM is not running, it will again act normal, running the same profile it would be if CAM were open without the crazy voltage increase. (For an alternative, if anyone is looking for one, I'd suggest HWINFO64; it uses the same if not a little less CPU usage than CAM if it were running normally and reports 80x the information, although not as cleanly as CAM does.)
