Mate that guide is donkeys years old.
I think he is running a Q6600 but not sure.
If so and that is idle then you are at the higher end of the temperature scale.
You should be looking low to mid 40's for idle and in the 60's for load. 50's if you can get it. (GO stepping CPU, B3 is hotter).
Did you apply aftermarket silver compound? If so then remember that it takes a lot of hours for it to settle, say maybe 200 hours for you to get your real long terms temps.
If your undure then clean it off and re-apply, remember just a thin layer, enough to just cover the writing on the CPU will do, too much will mess it up.
