Had some fun like this with a heatsink mod on my Nvidia 9800GT. The fan is replaced with a huge heatsink with individual heatsinks for each memory chip glued to them with a pad. Probably due to my hot running old motherboard (now replaced) the little memory chip heatsinks had started falling off. You would not imagine the trouble it is getting these little pads off. I used high strength alcohol and toothpicks to pick them off each chip a little bit at a time. It took me about a week doing some of it each day. A major job .
