Struggling with over-unders in plan

As above, get a fan. You are massively limiting the overall effectiveness of your workouts without one.

Keeping Cool and Power Loss

Negatively. Overly simplified, the body will begin to limit power output capacity when its efforts at cooling (via sweat) fail to reduce core temp. It is a preservation response that is meant as a secondary measure to reduce heat since the sweat is not successfully doing the job. As you found, air flow for effective evaporative cooling is very important and likely overlooked by many. A pool of sweat under the bike is not a badge of honor. It’s a sign of inadequate cooling.
