So do your VRMs have any cooling? One downside to tower coolers is they don't cool the motherboard area. I don't know if you are using a tower cooler or even what CPU you have, but odds are 1.45V is a problem for you. If your CPU temps are fine, and you aren't having any issues other than I high temp on your package/VRM, find a way to cool them. Better/less fans in your case, a different case which allows bigger fans, or perhaps mount heatsinks and fans to your VRMs.
