Lapping is great, takes a bit too long, but I have patience.
So why would someone consider removing the IHS, to use better thermal compound?
Could you put an air heatsink directly on the smaller sink inside the real processor sink?
just wondering if it would be worth the trouble to try it out.
Someone shoot me a link please

only an example, your Die may be different

Removing the IHS exposes the actual cores, which you can install your cpu cooler or waterblock directly onto. While this provides possibly the best heat transfer you'd have to do some mods to the cooler as the cpu contact point will now be lower than normal. It's also incredibly delicate from what I've heard. You can easily smash the cores in and render the cpu useless, as well as IHS removal only possible on a small selection of CPU's, while other's are soldered in. I believe the IHS also spreads out heat for faster/easer transfer, so in some cases it may not make temperatures better.

Correct me if I'm wrong on anything posted above..

Direct contact to heatsink or waterblock. It removes process of the heat being transferred from the thermal compound between the IHS to the IHS to more TIM and then to the heatsink.

Yes you can use a regular heatsink, but there are a lot of things that can go wrong. Too much pressure will destroy the CPU die. Not properly balanced, because of there is nothing to support other than the tiny die when first mounting it.

I'm not even sure if you can even remove the IHS on newer AMD chips. Usually it was an almost simple popping off method.

Now you speaking my language, Daring and insane. There is my first step to finding a reason to do it.....

I know the manufacturer put the IHS, and the compound on for a reason. I would assume they know what they are doing better than me....
However I quit assuming a few years ago, and trust a few overclockers way more than any corporation.
Thanks for the input!

Ah yes very good explanation. The IHS "looks" to be installed the same way. Even though I just got a 995BE, should that give me reason to potentially destroy a brand new (lapped) 940?
This thrill of destruction is costing me a fortune.

A better way to do it is too sand the ihs off, then it leaves a supporting ring of ihs around the cores, but leaves the tops clear.

I've done it before, twice on a Celeron D and Pentium Dual Core E2180, those are easy as they use normal TIM to bond the core and IHS, Anything else really uses Solder, so you have to heat it VERY evenly with something that gets pretty hot and hope it doesn't burn the core or rip the core off with it, really isn't a good idea unless you don't care if you might kill your CPU.
