Cool !
These types of fans are expensive so a good idea to do this fix. You're very lucky to have access to a CNC machine !
Does the game do any regulation of the speed ? I played it once when it was new and I don't really remember...
I thought about using a smaller version of this type of fan to pump out the heat of my SW cockpit. Of course running at a much slower rate. The SW cockpit "game" area is quite small compared to a regular cab, esp. with the 25" Amplifone so I thought it might be a good idea to use one like this. Should be possible to run it at a low rate and still pump out enough heat...
