Summary: I use this fan to circulate air thru my solar control panel, It's connected to a digital temp. controler. it moves massive amnt's of air, and with an outside (enclosed) application noise is not an issue! moving massive air is! and this fan moves it!!! I'm very happy with it, will be getting another for a spare.
Summary: This fan moves some air whoa! have two one for an intake & one for an exhaust. If you don't mind a little noise these are top notch in my book! They are pretty thick so be sure you have the room and clearance.
Summary: I use this fan as a exhaust fan in my basement. It fits in a existing dryer outlet perfectly. I set it working one hour for every three hours using a dialed timer. It worked great to keep my basement air fresh. The only issue is that its noise level is relatively high for a PC cooling fan. However, it is one of the most powerful PC fans on the market.
