Thread revival

I mean to remove the IHS from my 165 but I won't if I can't find a way to mount the XP-90C without crushing it.

I have a shim I popped off a Radeon 9500 or 9700 back in the days, I've checked the size and it will fit my CPU just right and I'm thinking of glueing it onto my 165. I should remove the black stuff under the IHS first, then what could I use to stick the shim? Generic superglue? Silicone? Hotglue? The less thick the better, because I don't know how tall the core is.

Do you think it's doable?
