Temperature Help

[BaitMaster]

Hey I got some questions regarding my CPU temps, SpeedFan, nVidia Monitor, and Asus Pc Probe shows similar temperatures, while Core Temp shows another temp, and I read that SpeedFan has an offset of 15 C. Which program(s) should I believe? Heres a picture: http://img229.imageshack.us/img229/2838/tempif0.jpg. Thanks in advanced, by the way I have a Q6600 at default speed.
