I may not have been clear enough but, you should notice that the bottom 
of the heat sink is NOT flat, one side is cut away, about 1/4" by 1/16" 
is cut away.  That cut away side must line up with the part of the CPU 
socket which sticks up higher than the top surface of the CPU. In other 
words, the bottom of the heat sink is notched, and if you don't line 
that notched out part properly, the heat sink will not come into total 
contact with the top surface of the CPU.  Some CPU fans have 
instructions that discuss this issue, check with the instruction sheet, 
if there is one, maybe they explain it better.  I'm just thinking that 
could be your problem, just check and be sure before you start throwing 
stuff away and spending more money.
