Do you have your windows tinted? that will help to keep your car cooler inside, besides the additions of privacy for your items in it. If you are thinking get them tinted find out about the legal allowed darkness in your area.
You could get a larger radiator or possibly a different fan setup. I suggest looking for a good radiator shop and talk to them. A different thermostat would also make a small difference. If I were you I would look at a different cooling fan. Most auto performance shops should carry a good selection of them. They would most likely know of a place that makes custom radiators as well.
