Well I bought some incubators and I am wondering on what kind of fan I need to use to put into one. I have a Hovabator and it doesnt that the fan built into it. here is what I am thinking about installing into my incubator. Will it be to big or create to much of an air flow? Is there such thing as to much air flow? Just wondering if you could help me out it would be awesome. http://www.marinedepot.com/IceCap_4...ighting-IceCap-IC5111-FILTACAF-IC5113-vi.html will this fan work? It is 4 inches or is it way over kil?
