Here is the deal... the sun transfers heat through radiation. That comes in the form of light that hits your roof shingles. The roof shingles transfer heat into your attic by conduction. the vents in the attic space create fluid air movement that removes the heat through the process of convection. The more air you move, the greater the heat transfer process capabilities are. The cooler the incoming air is, the greater the capabilities for removing heat.
Adding fans will not be enough to overcome the conduction of heat from the sun into your space alone. If you add some r60 insulation to cover the Attic ceiling, that will help slow the heat transfer from direct sunlight. In this case, you may be able to move enough air to create an optimal environment.
with that being said, another factor to consider is humidity. If the ambient air is very humid, that may slow the heat transfer process capabilities of convection. Lastly, bringing in high humidity into an attic space can cause other issues, like mold and rotten insulation. So there is a perfect balance one must accomplish in order to be successful at this. Ambient conditions will be the biggest variable one must consider when making these adjustments.
hope this helps.
