I believe the voltage range for that CPU is 1.13 - 1.4V.
If on auto the bios of the motherboard is setting it to 1.5v then that is way too high. If the cpu is at that voltage it could explain the high temps, well I think so anyway. I must admit I have no knowledge of that CPU but 1.5v on any CPU is a heck of a lot and temps will get very high very quick.
You have to ask the question as to why the motherboard bios on AUTO is setting the voltage so high. It could be a number of things. Have you tried removing the CPU from the socket and re-seating it? That could be worth doing. For some reason the motherboard is throwing too many volts at the CPU, whether it's a bad connection or whether the motherboard or CPU has been damaged or gone faulty I don't know.
If that doesn't work then I would suggest you read the online manual for how to set the voltage manually and get in and set it to say 1.2v as quick as possible after booting to avoid any damage if you can.
Not sure what else to suggest.
