Please understand this is NOT why we buy our motors this way and our motor are made to run for extended periods of time at 1.25 SF.

The customer wants to fastest cooling they can get on some parts, but a lot of other parts do not require that fast of cooling time.
Because it is a cooling fan motor, the hotter the cooling gas is the less load on the fan blade, but as furnace cools, the load increases, this is where we go into SF.
