Take a t-shirt, soak it in cold water, and use it to cover up your carboy/bucket. Take your fan and point it at your wet t-shirt covered fermenter. It will easily drop your temp at least a few degrees. I did this with my ESB last week, and it held everything at a perfect 68 F.
Just make sure that you're soaking that t-shirt on a regular basis. The water will evaporate fairly quickly. Just keep doing this until your krauesin drops, and then the beer will stabilize at ambient temperature. During the violent phase of fermentation, a lot of heat is generated. Doing this trick keeps things in check a bit.
I really want to build a fermentation chiller, but I just haven't built up the ambition to find someone to help me transport a big sheet of extruded polystyrene insulation as of yet. That will probably be my next homebrewing project of note...
