No amount of re-adjusting or putting on arctic silver
had a somewhat similar problem but found some causes and cures to my problem
My 2nd PC, a P3@933 was running near 50deg C
1> I tried a higher CFM fan, only 2 or 3 C improvement
2> Then applied artic silver 5, no improvement
3> conducted in-depth google-ing
4> Purchased exact-replacment heatsink
5> Performed a LAPPing operation on it thru 800 grit
and cleaned it with xylene
6> Reread *complete* *proper* Artic-Silver5 instructions from - their website (needs to be near-razor-thin layer)
7> re-installed and now run at 36-37deg C
(maybe refer to alpha-pal or hedgehog heatsink)
