these are the best fan controllers out there (their website could use some work though)

they provide variable speed control of the fan, not just on and off. they also come with a temp sensor and connection for ac compressor input and you can adjust the temperature trigger range.

 If you are going to rely on an electric fan for primary cooling, you have to have a good controller. The relay kit the flex a lite comes with is junk.
