For me these three aluminum Kühlkörperchen arrived quickly. These are a kind of double-sided tape (I assume times that of 3M imprint indicates a temperature-conducting adhesive pad) attached to the individual chips. One star deduction there is in my opinion, however, for the dimensions of the heat sink, because there are 1 large and 2 (equal) Small. Optimally, however, would be if one would have been even less of the 2 little ones. Then this would be no overhang and virtually no chance to touch other components (which is guaranteed in the other). With a little skill you but get it back so that they fulfill their task.
