I had a lot like this. And have tried many different methods.
In my opinion the best way to remove the heatsink is by squeezing it off in a vise. Clamp it near the base of the heatsink, evenly and tighten the vise slowly. You should see the heatsink bend and pull away. Bad part is more than likely you'll lift the printing off of the gold top (not always).
Looks like the glue that's on your chip should clean up farily easy. Brown foamy stuff. Most of it can be picked away and when you get close to the ceramic use MEK (Methyl ethyl ketone) a synthetic scouring pad and scrub away.
That's how I cleaned up most of my P60's and P66 gold tops .
Good Luck  |

Yep, the vise method is the best way.
I've frozen, heated, soaked and twisted them. |

| I agree with tlccomp. I have also had a great deal of experience with glued socket 4 Pentium's. The large vice method as detailed by cpuswe is best as I have never heard of it resulting in a broken cpu as often happens if one tries to pry off the heat sink. However, it will probably take the text off the gold. The text almost always comes off the gold. Nothing sticks well to gold. On the bright side it appears you have the foamy type glue instead of the evil epoxy. It will not give you much problem although it does appear to generally stain the ceramic where it was (note the stain on the pic of an sx836.) I do not know of a chemical to remove this stain without damaging text but someone else might. |

I'm back from the kitchen
so I decide to put heatsink and glue under the hot water 70-80° (pins are dry).
After 5 minutes I try to lever heatsink (easy) on each side.
It could be better but it could also be a lot worse
It's a pity that there is no a chemical method |

It feels like a long time since I took those pictures! 
Sometimes you have to rotate the heatsink in the clamp to encourage the heatsink off.
There are so many different types of fixings between the heatsink and the cpu that I think several methods must be used, or combined for best results.
Most of my cpus I put in the vice like you see, and it worked well for 99% of them. The worst fixing is that epoxy resin, it is very hard and always resulted in removal of the top printing.
MEK is often sold as plastic pipe cleaner in a small tin, look under the plastic plumbing section in your DIY store. OSMA I think is a big name.
This was the funny thread a long time ago...

| Well,, your right with humidity. But the Core should be sealed and if not 100% the air pressure inside because of heat should be high enough to prevent water/humidity from entering!? |

Ive had a Celeron Mendocino, First, I superheated it by boiling it, then supercooled it by putting it into the chest freezer into icy water, the cpu litterally jumped out of the water because of the shock of shrinking
try it
