25 mm fan (25 x 25 x10)

grabcad

Here is the rewritten text: I'm modeling a 25 x 10 mm fan, rated at 24V with a draw of 0.08A - keep in mind, though, that another rating might have different dimensions altogether. To get these specs, I've measured from an actual unit, leaving out the blades for now since they're not ideal for flow simulations. Be aware that cheap fans can vary greatly in size depending on the manufacturer.
