Aluminum will get cooler faster. What do most electric motors use for heatsinks? Aluminum. What are most stock heatsinks for processors made of? Aluminum. Does anyone make a steel heatsink that has half a brain? No.
Do you have a direct contact with flame inside your chassis?
Maybe in the topic of heating a steel and aluminum to outrageously high tempuratures and watching drop, aluminum takes the cake. However, according to that test, aluminum and steel CASES appear to score about the same. At one point I believe there was a single degree of difference.
