If you have a controller then you should set it to come on and off at the temps you want. Although that may cause your fan's to run almost all day and night to get it to the temp you want depending on your room temp. I have a quad fan that is adjustable to move up and down if your interested in getting a fan. PM me if you are and I'll give you more info on it.
