I have a stock cooler, stock voltage/clocked i7970. Max CPU vcore has been 1.18 in my runs. At idle it's in the mid 40's to low 50's (51ish). Running prime 95 blend I've hit mid 80's before realizing it got that high. In December I don't remember it getting above about 70. Could my high ambient temp (in the low 80's) be responsible? Any suggestions?
