Well, like the topic says, "off topic" ... this applies to heatsinks for
CPU's (particularly Athlon XP's)... I'm a hardware nut/overclocker, and
those in my niche generally only lap their heatsinks (giving them 3 degrees
better or so), lap the CPU's (2 degrees), use artic silver paste (3-5
degrees), or (this has just been discovered) use aluminum foil (2-6 degrees,
preliminary)... I wanna one-up these improvements by actually having the
heatsinks coated with a small layer of silver solder... I'm sure this will
yield a 3-7 degree improvement... about the same as going from regular fan
to delta fan cooling.

John,
Wow, That seems an excessive amount of work for a heat sink finish. What is
driving you to go to this level of finish?
We have upped or tightened our heat sink surface specs at quite a
significant cost and I can't say that it has made a significant improvements
in performance for the cost. I believe that the biggest offender for us has
been contaminates (dirt, metal chips) under the Isostrate thermal transfer
material that has caused a punch through during a Hi-pot test.

We have a roll of silver solder in house, and I want to try a little project
with a couple heatsinks...
One's copper, the other is aluminum... They've been lapped, and have
near-mirror finish... I'd like to take 1/32" off both and drop on an even
coat of this silver solder... I don't know how well they will bond, and
wonder if some chemicals will need to be used to aid in the bonding
process...
Or do I just let it drip onto the surface??
After the silver's on there, I'm gonna lap THAT finish to mirror-ish quality
and run some temperature tests...
Any advice??
Best Regards,
John Grabski III
