Temperature was just an example, i meant that when you set temperature then the fin with higher conductivity takes more heat and eventually has higher surface temperature.There is no issue....

Hi
Im really not expert in heat transfer, but i think Fluent is right. From fin to air, heat transfer(Nu) is a function of Re and Pr which none of them are relevant to fin conductivity.Lets write...
