As I remember I had to remove a plastic tape from the bottom of the heatsink
die, which the instructions from AMD said,'' A portion of the bottom of the
heatsink is covered with a rectangle of phase-change thermal interface
material'', which was only used, no other heatsink material was used!
Is this not suffiant then and another heatsink material should be used?
