There's no more fan in the box, so I routed my USB the same way you did, no worries.
Actually there is a fan according to realoem.com. but it probably doesn't need it. The ecu box is also the same part number as the n54, they just put some kind of plug to block the lower hole from inside the car. I took pics if anyone's interested but I'm just gonna run it how it is..no idea how to remove that thing.
