Connect a fan directly to the board.

I built an enclosure for my smoothieboard and it has a small fan to pull in cool air, what I need is a location to connect the power to the fan so that it turns on when the board comes on. I would like to connect it directly to the board since the design of the enclosure puts the green power connectors to the outside.

Is there anyway to safely power the fan from any of the other pins on the board? The fan is a small 40mm fan.

This is the case I designed. http : // www . thingiverse . com/thing:1340934

Actually I may have figured it out. Using the jumper to set the power to the small mosfets to VBB they will always be on. Now just to make sure I know what I am doing. I have added the jumper to Q8 & Q9, then I will not need the power in connector plugged in as it will be getting its power from VBB. Can I then use any of the small connectors for the fan?
