I have an approx. 3000 sq. ft. 2 floor CHC in NJ. During the most recent heat wave, I noticed the second floor is much hotter than the first when running the CAC (approx 5 deg). I assume that some type of attic cooling would help cool the second floor. There is insulation between the floor beams in the attic, a ridge vent and a gable vent. Can I install BOTH a whole house fan for cool nights and an attic fan for during the day when the CAC is running? Also, are the gable mounted fans as good as the ones that are cut into the ceiling? Thanks.

No reason you can not have both types. The gable mounted fan would be one type of attic fan while the ceiling mounted fan would be a 'whole house' fan. One problem is that the attic fan could draw cool air out thru the ceiling mounted fan opening unless you use one that seals such as It's more expensive but better in the long run. Might consider a solar powered attic fan. Also more expensive but no power from house to pay.
