blows out hot air from where? just give us an idea of the size of the fan (dimensions or CFM would help alot)...but basically any fan will work...just don't use something to weak...i use a normal house fan (the ones that go back and forth)... Hope that helps...Vokal
Im sure hes talking bout a small fan heater thingy! If it has 'cool blow' on it u could use it to circulate air inside a box or something! CWL
