Maybe I'm exagerating but this 060, latest mask, is gonna be working at 80Mhz

It's for an MKII, and since it's gonna be used on an A4000T for now, it's gonna be hanging down vertically from the CPU card. Don't think cooling past will be enouph to secure it.
What else should be used ? Don't like clips, but is SuperGlue gonna be enouph to conduct heat to the heatsink, even if it's just 4 drops on each corner ...
What if I later want to take off the heatsink and use another one ? SuperGlue is probably hard to take off...
....
Suggestions welcome...
