Hey guys, I was at AMD a few weeks back and showed them my star performance FMIC. They guy said it looked like it's been used before and that it's had a leak in the past which has been sealed. I placed it in a tub of whater and no bubbles and filled it with water and seems fine, but what do u guys think? (it's that yellow stain on the top). I also wanted to ask does anyone know what the black stuff is on top? it's like a black strip.
