reinstalling thermal paste ?

I put the original thermal paste on my 1.0 GHz Athlon myself. I used a thin
mask to deposit a uniform rectangular patch of paste on the face of the
heatsink, in accordance with the instructions that came with the thermal
paste. I'm using a pretty good (but very noisy) fan/heatsink combination.
The CPU runs too hot, so apparently I didn't do a good job with the thermal
paste. Now (much later) I'm going to redo the job. The ceramic shell on
this Athlon doesn't cover the top of the chip. You're supposed to put the
thermal paste right on the exposed top of the chip. Well, now that I have
to do it over I'm wondering what to do about the paste that's already on the
chip - how do I apply more paste yet insure there are no air pockets between
the old and the new paste. Should I clean off the old paste first? It
seems like that might damage the chip. Can someone tell me what I can do to
insure I get the paste on there the way it should be.

Thanks. Bill S.

If you're using standard thermal compound (white grease) you're making way
too much out of this. If what's there now isn't dry, just spread it around
with your finger on both the cpu core and the HS. Add more if needed and
then install the cooler. In the case of not enough / too much, too much is
better. A blob about the size of 2 BB's should be plenty. IIRC the size of
a BB correctly, 1 probably wouldn't be enough the way some HS bases are.

Clean off the old stuff with acetone.Apply the new stuff using a blob about

out using a plastic card(credit,library etc.)

I almost don't remember what a match looks like. Anymore when I want to
light a cigarette I just hold the end if it against my Athlon CPU. I don't
need matches anymore.

Acetone is a very aggresive solvent. On the heatsink that should be no problem,
but I wouldn't use it on the CPU. Any spillage on the laquered PCB components
could be very messy. High purity isopropyl alcohol, not the 90% stuff some chemists
sell, is better IMHO.

I just wet a lint free cloth with the actone, rub the old thermal paste
out,then use a second lint free cloth wetted with water and clean the suface
of the cpu. I don't use enough to form drops unless the cloth is really rung
out.

Also,acetone evaporates withiut leaving residue.
