Wrong sir, it's like the CPU heatsink it transfer the heat from the CPU to the heatsink, and the old CPU had heatsink without fan, if what you said is true why theu didn't just leave the CPU without the heatsink, if you look it's the same idea, and I think it will work better in our car, as the AC fan blows some air to the filter, so this way it will cool the collar faster and better, and like I said before have a read a review of a guy has done it in his Ford truck, and his temp of the oil went down but not like if it was a oil cooler but better than nothing.
