Quesion about CPU Heatspreaders

I figured you guys could stand a stupid question and not make fun of me...so here goes...
I was wondering what is in between the CPU and heatspreader.
Do they use thermal paste of any kind? Or, is it just the heatspreader metal directly to the top of the CPU...

You mean between the actual die and the heat spreader? It is my understanding that all AMD and many older Intel processors used thermal paste. Newer Intel CPUs actually have the die soldered to the heat spreader as the final part of the manufacturing process. I <THINK> they started doing that with the Prescott cores because they were so flippin' hot, but I don't rightly recall. AMD <MAY> also be doing that with their newer CPUs as well, again I don't rightly recall.

In any case, while 'capping' a CPU (removing the heat spreader) was a favorite among overclockers in the past to get another couple of degrees, doing so with modern Intels (at least) is just about guaranteed to get you a dead CPU. Even if you should happen to be lucky enough to have your CPU survive the experience, it is unlikely to gain you anything significant in performance. Solder conducts heat quite well.

OK, I was just wondering how that was done. Yes, I meant between the actual core (die) & the heatspreader on top of the CPU that you mount the CPU cooler to.
And yes, solder is a good heat conductor, and no I wasn't planning on removing it...

Basically, I've heard of two different methods; heat and cold.

Method 1 - works pretty well if you have a surface mount rework station. Since most of us don't, then next best thing is a heat gun. Generally, you put a dollop of solder on top of the heat spreader as a temp indicator. When the solder just starts to melt, you should be able to pull the heat spreader off. You have to break the seal around the edges first, though.

Method 2 - As with method one, you have to break the seal around the edges first, but the idea here is to cool the thing to a very low temp, around -10C or -15C or colder. Once it is cold, hopefully the solder will be more brittle than anything else, and you can gently pry the lid loose, fracturing the solder as you go.

Both methods tend to result in destroyed CPUs.

The part he didn't include was that if you do succeed you're a hero, and if you do it on a high end chip like a quad core extreme edition, you're a huge hero.
