Where to get thermal tape, and what brand?

[uOpt]

Where can I buy thermal tape, as used to put heatsinks onto VGA memory?

Are there difference between brands? What should I get?

I removed the RAM heatsinks from my 5900XT when I mounted the NV silencer but now I want to use an Aerocool VM-101 so I need to reattach them.

Not sure about Aerocool, the service seems to be complete trash. I really hope this works as planned.
