Manufacturers of lower class tend to save in production. They put as a thermally conductive interface which is located between the graphics chip and the heatsink, the thermal paste is not normal and slurred "termoplastico", for example, foil or strip. Such interlayers have only one advantage - they are cheap. After the purchase of such equipment, it is better to remove it, thoroughly clean the surface, Polish the sole of the heatsink and applied quality thermal compound. It can now be found without much effort, for example, Alsil.
