I just ran accross (and purchased) a very flat fan for anyone who is using one for cooling for their sump. The fan is about 1 ft square and only about 1" thick ( except fr the small base). It is also low voltage and because of that the motor is sealed. It produces alot of air movement and can be placed right on top of the sump. It was $20. If anyone is interested, you can pm me and I can send you a pict and model number. It also runs on batteries (power outage), 4 d's run up to 75 hours.
