I am not entirely worried about the heat so much as I am about the stagnant air. The room I have the brooder in is stuffy. I have the fan pointed at the door so that only some fresh air comes into them. In a sense, I am just trying to increase the circulation of the air in the room without creating extreme drafts, if that makes sense. The fan is on the lowest setting as well. I do turn it down/off when the temps reach a more reasonable level and the humidity/stuffiness goes away.
The brooder itself has a thermometer inside. At the moment it stays around 91 in the direct center, at the ground level, and the birds wander around as they please. During peak daytime, it can get to 99F so I try to control that a little with the fan. Figured an A/C unit would produce cold drafts that are even worse. Should I try bringing up the light some more? They like to pass out face down outside of the direct center of the light but not entirely in a pile. more like in a loose mess. Would it help if I just upload a photo?
