CPU temp: believe speedfan or foxconn's utility?

[pctwo]

I have a foxconn 6150 board, amd x2 3800 2.0ghz @2.4ghz stock volt. on idle, both speedfan and foxconn's ultility show I'm around 30-32C. On dual prime, foxconn shows I'm at 45-48C, but speedfan shows I'm at whopping 60-63C. yikes! I'd like to believe foxconn, of course, but should I? fwiw, foxconn is not even listed by speedfan under manufacturer.
