What do I use to reattach a glued heatsink to a video card?

I had a heat sink fall off of a video card because of defective glue. What can I use to reattach it that will not melt and provide the cooling that I need..:)|||I assume you're talking about a heatsink with no clip-on. That would require something like this:

Provided this heatsink is a small one, a dab of this paste and a firm but not hard push and a few hours to settle will secure the heatsink to the chip. If it has mounting holes for a normal HSF and mounting, you may want to use that for it's better cooling ability.
