This is exactly why I'm looking for those - I have very high quality copper heatsinks prepared for my rev. 6 68060 and I really don't want to use the thermal adhesive. If I have a properly working clip like that I can use 15W/mk Thermalright pad with it, plus it's far better support for a relatively heavy heatsink.
Yes, i need to install one in a a tower where an A4000TX will bemounted and the CPU card will be vertical. I don't want to permantly glue a heatsink on the 100MHz CPU but thermal paste is not enough to prevent it to fall on the other cards. Pity the 68060 socket does not come with a clip system like sockets by Intel/AMD.
