Fans will help, but with 2 250 MH's, you'll need some good fans, and you'll likely hear them, and then you will also have a fair amount of evaporation, so will likely need an ATO to maintain good balance. I just went to an ATO this summer because of this.
So, you'd have the expense of the MH fixture, plus a chiller, or fans and an ATO. You could get a pretty nice 8 bulb T5 for that.
