Hey All,
 
I recently bought a used "XSPC Razor 7970 Full Cover COPPER/ALUMINIUM Radeon HD 7970" its the older water block with 0.5mm fins. Well it didn't come with any of the blue thermal tape only the gray type and i wanted to know if anyone knows what thickness i will need to get. It will be for the memory and that spot next to where the gray type is used (the vram i think). I contacted XSPC directly and haven't heard anything back and its been a week.
 
 
Thanks in advance everyone!
