, see Section 8 - bottom of Note 3, Section 9 - Part 4 Note, and Section 14 - Item (I). The SpeedFan 4.32 / 4.33 +15c offset bug is common to all C2D's with Tjunction Max 100c Steppings, and is not confined to Quad Cores only. Since SpeedFan 4.34 Beta 23 requires users to jump through a few hoops in order to get it downloaded, I haven't recommended it in my Guide simply because some users may find this too cumbersome to bother with it. When 4.34 is release as a final version I will update the Guide at that time.
Also, if you don't feel 100% confident in the accuracy of your temps, then just follow the Calibration procedure in Section 9.
