I have AMD approved 60mm X 60 mm heat sink on 1.4 T-Bird. (solid aluminium with copper bottom) I want to upgrade the fan but not sure if the weight of 80 mm fan blower will be too much for the CPU socket. My motherboard has four holes next to the heatsink. Is there an adapter that I can use to mount an 80 mm fan on this heatsink using those 4 holes so that I do not weight the cpu socket?
