Yeah, 74f is a little on the warm side and a simple swamp cooler is definitely an easy way of controlling ferm. temps therefore getting an instant increase in the quality of beer you produce.
It might not really be of much benefit for the present brew as the initial, vigorous, exothermic stage of fermentation is probably winding down, so you'll want to keep it warmish to help the yeast finish off and do some clean up, conditioning, where some of the off flavours can be dissipated. Not sure of what the best temp range for the wyeast ESB 1968 is, but being an English it might not throw overly hideous flavours at the temps it hit.
