I didn't even think about heatsink, it is too big.
I have seen that the connector is too big for VIN port.
I didn't check how much current it draws, but i do believe it is a 12V fan, so it certainly won't run at full speed.
I will wait for official fan, i won't experiment with this one, i don't want to destroy the board, and i do need every usb port available.
Thanks for clearing this up.
