I don’t understand why you’d want to remove the heatsink? The good thermal adhesives are pretty much permanent. Personally, I’d find a heatsink that you could screw a 40mm fan into and use thermal epoxy to permantly attach it to the CPU. That way you can replace the fan with any generic one down the road without removing the heatsink itself.
That’s assuming you want/need a fan. If you don’t, it’s even less of a reason to remove the heatsink.
Any sufficiently advanced technology is indistinguishable from magic. (E.g., Cheez Whiz, RF, Hot Dogs)
DRx2-33/66 is a rare CPU. If you epoxy a heatsink onto it, you are destroying much of its value as a collectible. Not to mention, you're making it almost impossible for the next owner to determine what the chip actually is, since the bottom markings don't clearly indicate the model or speed.
The adhesive pads that Cyrix used are easy to remove and don't cause any damage to the lettering when taken off. It would be nice to determine which product they were using, so we could possibly buy more of them.
I personally feel the best option for Cyrix chips without heatsink is to use a 3D printer to create a plastic bracket. The bracket sits between the CPU and the socket. Then all you would have to do is cut some aluminium heatsink and wire it onto the bracket. I have several such brackets for my 486 chips, and they work great.

I have three of the PGA168 SXL2 chips and the heatsink matches the QFP144 version for the most part.

As Anonymous Coward pointed out, you would depreciate the collection value to permanently adhere a non-original heatsink. Even an original heatsink, if it is removed or falls off and the lettering is damaged, you lesson the collection value. I agree that using permanent thermal epoxy may be OK for non-collectable chips, for chips which are common, or for chips in which you don't care if the lettering is ruined. The SXL2-66 QFP144 on PGA132 and DRx2-33/66 are rare and maintain a high resale value.
Plan your life wisely, you'll be dead before you know it.
Doom benchmark results are always of interest - I also used to watch your youtube-videos since you seem to have so many of these "old" chips. Have you ever thought about "donating" Doom scores to Anton's http://www.complang.tuwien.ac.at/misc/doombench.html?

good idea.
I will send an email to Anton Ertl with detailed specifications.

Great - some exotic entries are always cool!
His page is a subtle but timeless ode to Doom.
