Which cheap incubator fan to buy?!?

With this variable speed cord:

You can adjust the fan to the perfect speed to circulate the air without adding additional heat.

That's what I use too.

With a small incubator is the fan necessary? Let's say an incubator that fits 2 6 qt tubs in it.

I would think so - just maybe a smaller fan. Heat rises and in an insulated environment, there can be quite a temperature change between the top and bottom.
