One thing to think about if you are going to combine a whole house fan and an attic fan is that the whole house fan will move a lot more air than the attic fan. Thus, when the whole house fan is running and the attic fan feels the need to operate, it may free spin the attic fan faster than the motor is actually turning it. Can be very taxing on an electric motor. Similar to reving your car engine all the way to red line without any load (being in gear and moving).

Our customers that have the whole house fans, love them. In this area they really are a great way to keep things cool, without the need for an A/C. But the air has to be able to escape in an efficient fashion. ChipJ, get some larger gable vents installed. If the access is good to the attic, it should be an inexpensive option to get the most out of your fan. And by going bigger, the siding just needs to be cut to fit the new opening and not replaced or removed (unless it is vinyl, than removing and cutting is the best option, but still very easy).
