Thanks Playwell, greatly appreciated.

Off the same board you need to put a transformer for the 12 DC for the fans. I used a Dicksmith one I had lying around with 3,6,9,12 volt switch on it, so I can slow or speed up the fan for air/heat circulation depending on what worked best. (Testing over 2 weeks) I found that 9volts is perfect for even fast heating.
Hey there Playboy be careful with dropping the voltage below that rated on the fan as that will cause it draw more current and therefore possibly burn out at a very inconvenient time. I'd keep a spare fan to hand just in case mate.

Are you sure about that? I've also added a fan to my incubator this year and like Playwell am using an adjustable transformer and have found 9 volts to work best. How does lowering the voltage cause the fan (effectively an electric motor) to draw more current? V=Ir so lowering V will lower I, unless r somehow decreases with V... is this the case?
