Thats mucho too high! In fact the release bios usually reports a lower temp than it really is. So I would take your Heatsink off and reseat it to make sure you are getting good contact, etc. Do you have thermal compound on the CPU? What Heatsink do you have? Whats your voltage? and Yes the bios reading is on Full Load.
Just for your reference, on Full load in the bios at 1.85V with alpha/Delta/Artic silver I was getting 35C with the correct reading off of beta 05. The release bios had me at 15C. The release bios was off for me by 20C.
