Cooling Fan Manufacturer geometric properties and thermal resistance

"Cooling Fan Manufacturer" influence the shape of the base of the radiator heat conduction how much? This question sounds quite incredible. In fact, at this stage the use of the radiator fins of the metal material (such as copper and aluminum) of high thermal conductivity, coupled with the base thickness is not large, so the impact on the "Cooling Fan Manufacturer" cooling effect in general and obvious. Fixed CPU core with a thickness of 10cm aluminum block, the upper fin cutting into the bottom surface after grinding: As you can imagine such an experiment. Such an open "Cooling Fan Manufacturer", ants can almost guarantee it will happen when the machine does not need too long.
