Oh and for the voltage warnings. Make sure all of your mobo drivers are up to date and reset your bios. I actually suggest shutting your pc down, powering off then unplugging the power supply, and pulling the bios battery out of your mobo for at least 1 minute. Then put it back and reboot. (Don't forget to redo your bios if you made any changes originally). If that doesn't help update the bios if possible. You may have a bad board if none of that helps. Make sure there are no other programs attempting to change power settings or speeds. One thing you can do to help your temps with your current equipment is get some real thermal paste Arctic Silver 5 is one of the best. Just wipe of the stuff on there right now with rubbing alcohol, let it dry and spread on a extremely then layer of the thermal paste with an old credit card or something (plastic cards work best) Check out youtube for some instructional vids if you aren't comfortable yet.
