I myself have found hand fans to be a big help in keeping cool during an episode. The fans I use are to be found at

Although they have several catagory of fans, you will probably just want one of their "plain wooden fans". Click on size large plain woodfen fans. The one I currently use is PF1246, which is 27 cm long folded, about 10-3/4 inches. Now THIS is a fan, and the largest the sell.
My friends, coworkers, and AA members have become use to my unfolding the fan every houror so.
Besides, when folded up and carried in your hand, it is a perfect phallic symbol, just what we eunuchs need.
