Why buy a shim

[joker_927]

I was told by numerous people that I MUST buy a shim. MUST MUST MUST! So okay I went to a ite and found a shim for $8 and $15 shipped. That's a lot for a thin piece of metal. The website says that they are highly NONconductive and the shims go through an extensive treatement to make them that way. I go over to CompUSA and I see a copper shim for $2.99. I didn't look at the back of the box, but I read the front, and it said nothing about conductiveness. If conductivity is a MAJOR problem with shims, how can they sell copper ones? Also, isn't a shim a shim? It is it then I'll just run down and pick this $3 one up, and save me some time and money.

Are there really different quality shims?

Everyone recommend these shims.

This is the shim in CompUSA although priced differently

I bought a copper shim for $4 shipped and all I did was put a little scotch tape over the L bridges.

There is a lot of articles and disscusions here and at other forums about "shims".
Personally I don't use them and never have.
Someone had posted the same question a week or two ago about this and I think it was surreal that had said that shims are not recommended.

Well, If you buy a 550 gram Heatsink and put a fat fan on top on it, when you turn your computer right side up, that is a lot of pressure, so I'm going to buy a shim. I just can't decide which one.

One site I looked at said that only difference between a copper and anodized was thir conductiveness. The ONLY bad thing about a coper shim, was that is it ever moved, it could short out your bridges and fry the chip. Well with a 550 gram Heatsink, a fan, and the fact that the shim sits on the four rubber feet of the processor, I don't see how that shim would EVER move.

I'll see who replies, and what else I can find on the interent, then propbably just go buy the darn coper one at the store. I wish the stor sold anodized ones, that would be the best. Know nay stores that sell anodized shims?

If you look at the shim, you will see that it doesn't sit on the four pads, it actually has cut-outs to go around them. The shim helps the HS sit firmly on the core. A good shim will not only be an electrical nonconductor, but a thermal nonconductor as well. Some of the new socket A chips get very hot, and hopefully, most of that heat is transfered to the HSF. When the HS gets hot, it will heat up a thermally conductive shim, hence melting and scotch tape protecting the precious bridges.

Your best bet is probably something like this .

Wow, I like the description on that one.

Seems too simple because all it has is an outline. Still, you may have persuaded me to buy ANOTHER product from coolerguys. I buy a lot from them.

Personally I think a good non-conductive shim is a great way to prevent core chipping when installing the cpu fan.

<---- Has a 1.4 T-bird in the closet with more chips than a can of Pringles. (r&r'd the cpu WAY too many times. a shim would have been a big help)

On the other hand I have fried a 1gig T-bird with a copper shim so I would stay away from those.

Cool.

About the 2400+ being 2.0 ghz,

Is this site crazy? Tons of sites advertize the OEM version as 1.93ghz. WHY!!!!

ok heres what i think, if you chip your core, you did not take care in installing a cpu, amd makes their cpus to withstand the pressure of heatsink clips, in fact the pressure helps ensure the best thermal removal properties, shims are nice i spose if you are removing and putting the cpu on often, but amd designs their chips to be installed without a shim, just a thought
