Alright when i took apart my 8800 GT i noticed that the GPU is exposed. Im not sure how i should clean this. I can get the actually chip itself clean but around it its like a valley where theres a but of things sticking up.. and i cant get all the thermal paste out of it. Do i need to get the paste out of this area even though its not making contact? If so whats the best way, thanks.
I usually use acetone. It seems to really dissolve heatsink grease (much better than alcohol), then I usually finish up with alcohol either isopropyl (rubbing alcohol) or ethanol because I'm not sure if acetone leaves a residue, but I know that alcohol does not.
