no, i've been trying this out since the secc pentium II days and where sometimes you get 3-5 degrees, if your heatspreader wasn't flat to begin with, it'll drop ten

or if you had a really hot proc it'll drop ten also

think about it this way:

the difference between a good tim like arctic silver versus just white goop or colgate toothpaste or something is 5 degrees right? (i know dan tried toothpaste and it turned out to be great untill it dried)

we all know that the best thermal joint is no thermal joint (aka continuous) so if you can get 5 degrees off of a tim joint and there's one between the cpu and the heatspreader

well, there's your first 5 celcius

take another 2-3 from lapping the hsf and another 2 from your heatspreader being slightly convex or concave depending on how you look at it

and divide and then multiply the total by the c/w total of the cpu of yesterday and a more modern cpu

you've got like 15 degrees if you happened to get all the worst batch jobs in a row, which i'm sure you won't so 10 is a reasonable estimate of what everyone will get if they also had an x2, or prescott, but you'll have to lap THROUGH the heatspreader to get rid of that

way back and none of the pics work anymore:
