Fan in Comsol

Is it possible to make a fan that spins by itself to produce an air flow? I know the other option is to just have an inlet somewhere with a fluid flow rate, and get the fan to spin because of the flow rate, but i am trying to get the fan to spin, and initiate the flow rate. My goal is to model the cooling system of a gaming system, so i want to be able to have the fan have different speeds to simulate when the system is just turned on and in standby and also when it is operating at maximum capacity for a long period of time.

Hi
modelling a full rotating fan (in 3D) is a major task.
But to simplify COMSOL has some fan BC's that allows you to define the fan propertis, pressure loss or volumetric flow, depending on your fan curves.
in v4.2 if you need to analyse the pressure drop you must distinguis the up/down BC values of the pressure

Good luck
