Peltier Question/problem?

[84 CRX]

I have a water cooled processor right now. I also have a 80 watt Peltier.
The question is, how do I keep frost and condensation from frying my motherboard and/or processor? I have gone threw about 4 processors and 3 motherboards before I gave up on the Peltier.

Is there an easy fix to the problem?

My processor is an 1800XP unlocked to 1754mhz.

Please HELP!

I am sure you realize that your 80 watt pelt is not enough for your XP. Condensation prevention is just a matter of insulating everything. Pro Cooling has a good article on condensation prevention. My method is below.

Coat your the inside of the socket, area surrounding the socket and the back of the board behind the socket with your choice of conformal coating and insulate with neoprene. Remove the feet from you CPU and coat the exposed circuitry with conformal coating. Don't forget the dielectric grease in the pin holes of the ZIF socket. You may want to cut a thin strip of neoprene to cover the locking lever of the ZIF socket. This is not shown in any of the following photos.

Make a blanket out of 1/16" neoprene to cover the whole package.

If you are using one pelt, you will need to make a neoprene gasket to surround the pelt between the block and cold plate. With dual pelts, you can just run a bead of silicone around the pelts between the block and cold plate. Then surround the coldplate with neoprene. I found it easier to insulate the whole block and cold plate as a package. Note the 1/16" CPU blanket in the previous photo is also in the photo below. DO NOT use two sheets of 1/16" neoprene.
