We have a solar gable mount fan on the Ohana (as we have a gable end on the ohana attic).
We added the ReFlectix radiant barrier prior to the attic fan, and then added the solar attic fan, each step has helped, but working in the attic is still toasty - in the ohana, it is cooler (and we do have an area in the shower that has an opaque skylight, with no radiant barrier .... the floor is nice & toasty right there, ....good for a shower....but it does remind us how nice the radiant barrier is...)
We chose the gable mount because we did not need to pierce the metal roof or worry about the metal roof flashing dilemma (see other threads on that...) and it was available at Lowes & very easy to install in the attic.
One other thing that is major.... do you have enough window/door (screened) space....esp on the tradewind side..... we have found that adding more tradewind side windows has helped (and shading windows that get the afternoon sun)
