clean out your heatsink and all the dust from the inside of your case. take off the intel heatsink, clean off the processor and heatsink surface with some isopropyl alcohol , at least 70%. put on some artic silver, just a small line down the center. reapply heatsink .
test your temps again.
P.S. gosh those were very high temps. I hope you havent damaged any of your hardware. I bet the aux was your southbridge temp .
