Thanks, everyone!

Since there is already a thin layer there, I'll just leave it as is
instead of adding more.

If it wasn't for you guys, I would have made the mistake of putting a
thicker coating on.

The only problems with putting too much on are the cost of the paste
and what squeezes out when you re tighten the heatsink is messy! In
the years when I made my living servicing PC monitors & PSU boxes,
about 4 or 5% of PSU blowups were due to insufficient heatsink
compound. In every case, replacing the blown components and using
sufficient paste provided a permanent repair.




I've made money from repairs too. I've seen the damage that happens when a
power amp got too much paste to allow proper compression and conduction of
heat. Fixed it too, with proper method. I said this twice now, because I
don't want this point to get lost. If thick film was the way, there'd have
been loads there already, and the Mysterieux said there wasn't.

Maestro Mysterieux, I've often left the original there like you're
suggesting. Check that it's ucontaminated by even a single hair though. And
smear inwards like I said in that other post. This will give it a bubble-
free profile and also remove surface contaminants to a large extent. But if
it's got furry while you were working, replace it for sure.
