Copper shims...are these a good idea

or a waste of money....just thought I'd ask before I busted out the $10 for one.

I believe they are a very wise investment since it may save your core from being crushed or chipped. As for heat they wont help a bit. In some cases they may raise temps a smidgen. If you don't remove your heatsink often I wouldn't bother wasting your time or mony on one.
I think it depends on your CPU and heatsink. For Intel processors it is pretty pointless. If you use a HS other than an Alpha or Taisol on your AMD, they may not be a bad idea. Apply one with thermal compund and temps should reduce a bit under heavy load. It did for me anyway.
Well, I planned on going with an Athlon 1Gig. with a Global win FOP-32. Would shims to protect the die be worth a risk in raising the temp?


Absolute waste of money... I bought several copper shims thinking they were a good investment... bah, $30 down the tubes. According to a review on the main site there is some evidence that they actually degrade cooling performance.

More importantly than that though, they are just a hassle. I got one of the shims working on one of my CPUs, but when I removed the heatsink and tried to reattach my computer would not POST. Either the shim was preventing my heatsink from contacting the processor right, or it was connecting the some of the L#s (it may have slipped on to them or something). After almost RMAing the damn board, I found out it was the crappy shim.

In the end, they are more trouble than they are worth. Save your $10 and go catch a movie or something instead. There's just no substitute for simply being careful when attaching your CPU.
Thanks all,

I'll start lapping my FOP-32 today. Hopefully I can find a good deal on silver thermal paste.

The copper shims are a very bad idea, I used one when I first put my system together with a 1ghz t-bird and pro-2a mobo and fried at least the mobo, haven't tested the cpu yet as I ordered another right away and used the GA7zx-1 the wife had gotten me, until the pro-2a is rma'd. Unless you put super glue on the corners of the shim to hold it in place it will make contact with the transistors on the top of the cpu.
