I've found having fan control nearby helpful. The pull chain to control speed of the ceiling fan is within reach as is the remote for the floor fan. So I start on slower speeds then crank them to full blast once I'm really into the ride.I started to pull away with some of them but we were asked to slow and I did. They were putting out more than I could anyway. Sometimes the legs don't want to know about 4w/k let alone 5 or 6. Put stopping for 2 mins with fans on and legs tightening is not good, at least not these aged legs.
It certainly makes a difference too. I've just got one box fan and no central AC at the vacation house -- and when I ride there its always much more of sufferfest as the room just gets too hot/stuffy, even with the windows open.
