Lapping the GeminII?

Nope. I haven't had the chance to see one yet.

I can understand lapping an old contact plate that has been used and reused to the point of actually having wear and tear, but what about a brand new heatsink?

It's the same thing.

Think it needs a lapping?

Could you line it up with some grid paper? Check the lines and if it is straight then it is fine. I know this method isn't as good as using proper tools like how Quakindude does it, but it works well enough.

Lapping is always optional. You could have a brand new heatsink that right off the bat doesn't have a surface that you like. Regardless, the surfaces usually are like that for a reason (especially on higher end models) and shouldn't affect performance all that much. Lapping will pretty much always bring better results (no matter how little). But for experimentation it's always good to give it a shot and see what happens.

Lapping voids the warrenty of course. Right?

Also, since the GeminII is so big and top heavy, any tips abou how to go abou lapping it? And how about lapping the CPU itself?

I'm actually more interested in lapping my CPU. From the pics of any CPU lapping I have seen, the edges are almost always higher than the center. Is there any way I can mess up my CPU? No water when lapping, of course. Whats a good finishing grit of sand paper?

It's almost totally unnecessary to go higher than 800 grit on a CPU. It is also much easier to mess up a CPU while lapping. I'd recommend using masking tape to cover the sides of the ihs so copper/metal shavings don't get anywhere they are not suppose to be. Extreme caution is needed when doing something like this.

But I should still try it?

I'd have to see what the surface of YOUR heatsink looks like.

Aha, I'll get some to you!

I guess your the lapping expert!!!

[Tyreal]

Not really. I've done it a few times but I hardly consider myself an expert at it.
