I have a visiontek geforce 3 ti200 with the standard fan and heatsink thing (tahts the big square blue thing i think, and its on the ram chips too) And i took out the two black tab things, but i couldn't get the dang thing off, i guess it has thermal paste or something, so how do i get it off? i took out the fan itself and my borb wouldn't fit in it , thats what i'm trying to install...
