They're fairly solid and strong so I doubt you'd break it. To get off heatsinks that are glued I usually spray the heatsink with freeze spray, then put a credit card under one corner between the heatsink and chip, use a flat blade screw driver to twist. It should 'pop' right off.
Thanks, that worked well although I didn't use the freeze spray, just a small flat screwdriver and put some torque on the heatsink on a couple of edges and it popped off.

Now, what to do about the "glue"? It doesn't look like any thermal paste I've used before. It's shiny and hardened like dried glue. What is the best way to remove this stuff?

I'd be tempted to use IPA alcohol and let it seep under the glue. That sometimes is enough to pick it off. But it can take a while and a few rounds of adding alcohol as it evaporates quickly.

If that doesn't work, stronger solvents like acetone would be next. And then WD40 (with care, and that needs careful cleaning afterwards).

Don't power anything up if the board has non-evaporated IPA left on it. A polar molecule and conductive.

Yes as dml says. Worst case you might need to get some 'wet and dry' fine sand paper and slowly take it off in a circular motion. But first try what dml says, let it soak in IPA for a bit, then get a sharp flat blade and scrape it off.

Ok, yeah, thanks for the tips guys.

It tooks about 6 times, it was stubborn stuff. I would soak it a bit in IPA and the used a flat exacto knife to gently scape a layer off. Rinse and repeat until it was all off. Then some alcohol and lint-free cloth to get any residue that was left.

Now to put on the new heatsink and noctura fan.

Installed the new heatsink/fan combo on the cpu. Put a little artic silver 5 on the 68060 beforehand. Perfect fit.

I have a question though. The back of the CT60e really has no support from the ram slot to the psu connector. It looks like there is enough room under it to put the original metal psu bracket back (of course it would have to be insulated) and have that as some support.

Has any tried that or know if the bracket will actually fit under the CT60e?

It doesn't, but there are other solutions.

Hi,
Do you have a link for the heatsink and mount you used ?
Thanks

Yes, see the quote below from earlier in the thread. The heatsink is the one @dhedberg recommended. Digi-key was out of the blue, but looks like they have some in stock now. Of course you can also get it in yellow as I did. The fan is the Noctua NF-A4x10 FLX. The stock fan from the heatsink/mount comes off and the Noctua goes in. The Noctua is taller so you will need new screws to attach it to the heatsink. I found #4 3/4" sheet metal screws work great.

If you're prepared to pay for it here's what I consider an optimal solution:
https://www.digikey.com/product-detail/ ... 45-1601-ND

It's a heat sink with a fan that fits the 68060 perfectly and snaps on to it underneath. It allows you to use regular thermal paste and it can easily be removed and put back any number of times. The construction has springs which will push the heat sink down. Replace the fan with a Noctua NF-A4x10 FLX and you get a close to silent fan with improved air flow. The Noctua can be mounted in the same holes as the removed fan, although you'll need to replace the screws with a set of longer ones as the Noctua fan is a bit taller. Best of all? It all fits within the original case with a fair margin!
Digi-key (and most places) are out of the HSF-48-19-B-F but the -B- stands for blue. There is also a yellow -Y- version with the same specs still in stock at digi-key if anyone is looking at this solution for their CT60s (I just bought a couple for mine). https://www.digikey.com/en/products/det ... -F/9093756
