here is what I have come up with thus far to have an independent reliable fan + timer. Total cost I think isnt too bad...
Dual 80mm component cooling fans with USB connection ( bottom and top)

Intermatic DT620CL 15 Amp Indoor Astronomic Digital Timer

The USB cords could be run out the drain hole ( as I understand - maybe Im wrong - not even sure how) -> attach to the usb adapter and timer...This would solve the fan timer issue...I think...
Any thoughts?
Thanks.
