was putting my Corsair Vengeance ram back in my pc and my hand slipped and I popped off the heatsink to it lol. It wont hold properly now. What is used to keep those suckers on, looks like double sided 3m tape??

And if its not thermal tape thats what i would use to put it back on with

IMHO, what you should use Snakegs is Thermal Epoxy like this which is specifically designed for permanently bonding RAM, as well as other heatsinks, and is typically better than a Thermal Tape solution..It's not the first time here I've heard of those dang Corsair heatsinks coming off/falling off..Of course you can always RMA them, but I would fix them permanently with the epoxy and not deal with the RMA hassle/inconvenience..Good luck.
