The water doesn't need to evaporate off the coil; the coils are designed for it to drip off to the drain pan and out to a hose or condensate pump.

Some water drips off, yes. Some water remains clinging to the coil and contributes to mold growth, especially if it's allowed to remain for long periods of time.

After all, if there were no residual clinging water then the fan couldn't "blow condensed water back off the coil", which was your original concern. ;-)
