My CnQ is handled quite nicely by my bios and Vista. Even when both cores are under intense load it never runs up above 49C, thats if its being reported properly. Using an AMD stock cooler and a simple case fan on a Athlon 4200+
It really could be BIOS. Sounds like my old system, I updated the BIOS and suddenly I was 130C or something. Rolled down and it was normal. I just realized Vista does CnQ, and I still need to upgrade my cooler.
