those little zalman vga ram sinks...

how sticky are they supposed to be? because mine just keep falling off at the slightest touch. They seem to do the job OK though. I thoroughly cleaned off the residue from the stock cooler.

A lot of those little vga ram coolers (and NB coolers) use thermal adhesive. It gets softer the warmer it gets. And less adhesive. Kind of counter-productive.

Typical fix is to use thermal epoxy.

heh, I've never had a problem with them falling off. I poped mine off (sharp twist) of my old video card and stuck them to my new one without so much as changing the thermal tape, it's nearly a year later and they are still holding strong

Like the other guy said, if you never want them to come off you can thermal-epoxy the sinks to the card.

Get some thermal epoxy and mix it 50/50 with AS5. It will stick good and you will be able to get it off if you ever want to. You also will get good thermal transfer.
