I’ve played with the controller. It didn’t do much. In my experience, more fan area is better than smallers fan kicking out more speed. Use a wifi power strip ( eg https://amzn.to/2Qlv4eN ) to turn them on/off as you need them.
You just need convection, it doesn’t matter how fast that air is moving as long as it is moving. Speed helps if the fan is far away. Try moving your fans to the 1 or 2 o’clock position to the side of you, so your back and front get some air. Also try an up high and down low fan.
