These fans are small and don't move much air, but I bought three of these to cool electronics and they're great for that. I don't think it would be very useful to actually cool the room, but they are small enough to put in closets or under tables where you have a lot of electronics just to keep air circulating and dissipate heat. They're pretty good for that. I think if you want some air movement or even white noise that's great. But if you're looking for something to keep you cool in a hot room, they make the same larger version and this would be your best bet.
