I just read this article and it really shows the need for independent clamping of peltiers to provide enough pressure for efficient cooling. Just thought at little reinforcement may help explain why some peltier users find the performance a little disappointing if they are only using sufficient clamping pressure to hold it on to the cpu.

One thing that should be mentioned is every pelt I have used has been slightly concave like a Northbridge chip. A little extra thermal goop may be required. Like installing a HSF on a Northbridge, I would recommend disassembling the coldplate/pelt/waterblock to make sure you have proper contact before using it on CPU.

Colin, I found this also, I usually use a few blobs of superglue along with my arctic silver and (carefully) clamp the block, pelt and cold plate in a vice untill it sets to get it all fitted up as best as possible, seams to work OK.

do u guys put a thin layer of as2 between every surface being used for: die/coldplate/tec and block?

especially wondering whether or not your applying to both sides of pelt.

thanx

Thats a definate YES, you need thermal paste on both sides of the pelt.

I am glad that someone is addressing this. I had one heckof-a-time mounting the cold-plate, pelt, and waterblock. Attempting to tighten the contraption, and keep everything in place is a nightmare, no matter what type of thermal grease used. I used Arctic Silver last night, and it was "slippery" also. The process used in the link above seems like a good idea. but not promising if you have a smaller block. If anyone has any other suggestions, please post them.
Thanks
