Adding a Fan to my Incubator

[Ducks81]

Hello- I was trying to get a small fan to add to my incubator for air circulation since right now it’s still air a still are homemade one. Can I use this very small 5 inch portable fan somehow? Or do I need to use a specific type of fan for the air flow? Please see the photo. Thanks!!!
