You must use Blown over, Motor Cad does not calculate the fan characteristic, you must enter the values by yourself. This is what I suggest, in the Blown Over tab enter the flow velocity and a typical speed degradation curve. Iterate the flow velocity until your temperature is belowe limit. Load the motor model into a CFD software and check the speed profile along the motor fins is similar to the speed profile you input in Motor CAD.
