Well the system I pulled it out of is an ancient no name brand Pentium 1, so I'm betting they went out years ago.

That almost looks like a thermal epoxy... what kind of HS was it tied to? Aluminum, Copper, ???

When you got the HS off the cpu, what did it look like?? was it clean or did it have junk on it too?

Um... on another thought... there was a time when the thermal compound was a tape ... (actually it was a tape with a thermal epoxy (see the glossy edge on the far right hand side of your pic?)
and when the CPU got up to temp (usually after several hundred hours of being cycled on and off) the epoxy cured.

You might try a little acetone (I'd use a q-tip) dip one end into the solvent and see if some of the epoxy comes off (from a point in the middle of your thermal compound). Please be careful using the acetone since it has a nasty habit of liking to dissolve many plastics (actually it melts many plastics).

Edit: BTW... if acetone doesn't do the trick, then you'll most certainly be relegated to some kind of grinding method... (of course, you might call the manufacture and see what kind of compound they used in the first place and you might inquire how to get it off).

That CPU presents the perfect opportunity for lapping, although I doubt that an old P4 is even worth the effort to salvage.

I've read at least one article where the writer begins his lapping project by filing the chip before the sanding process. Selecting a fine threaded flat file would at the least be better than grinding.
It's not a P4, were did you get that? I pulled it off a P1 MMX 200Mhz... Lapping is allot of extra effort as I'm just looking to put it on a low end GPU with an even shittier heatsink.

Picture... And I said it was grey.

It wasn't that hard to get the heatsink off the CPU, popped it off with a flathead.

it's refusing to come of the heatsink though, looking like I'm going to have to sand it off. Heat gun did nothing to it.

But the root problem is still to get the stuff off.

I'm looking to repurpose the HSF off an old P1 MMX to use as a replacement for a low end GPU. The original is loud, dinky and overheats...

But after managing to pop this block off the P1 I am now stuck trying to get whatever kind of gray plastic like thermal medium ff of it. 91% alcohol and Arctic Cleaner don't do anything to it... Suggestions short of grinding it off?
Try acetone or lacquer thinner. Then xylene or toluene. You could also try Goof Off. Be careful. Any of the previous can melt ANY plastic components on the heat sink, including wire insulation.
