[MW:30792] Heat input and cooling

Dear all
I am confused about the following statement. Can anyone tell me the reason.

High heat input causes slow cooling and low heat input causes fast cooling.

I understand that cooling is a function of temperature differences between the metal and ambulance system. If high heat input causes high temperature then temperature differential should be higher than low heat input.
Can any one tell me the reason.
