    "Attach the Fan" picture.

    "Secure the fan to the electronics cover so air is drawn through the laser cut part."

    Pointless comment? How exactly do we know which way the fan is blowing?

    I can never work this out from the fan blades and we don't know until installed which way the fan rotates?

    No arrows on my fan. Not a problem as long as the fan is in position that can be accessed when the printer is complete.

    It is also usually standard that the cable is on the exhaust side of the fan.

    The sticker side is (in case of the bigbox fans) always the blow-side. I don't know if this is standard, but it looks like it. But the BigBox fans indeed have no arrows (I was looking for them also).
