Not sure why cutoff voltage would make the speedo go. Your rollout is a little low for a 5.5, but that shouldn't make it run hotter. Note that more drag brake will make the speedo run hotter.
It isn't unusual to run a fan in mod 12th. I have used one with my Flow WT ever since I changed to the Motiv motors just because it helps reduce fade at the end of the run and keeps the car from feeling 'soft' with the faster 3.5t instead of the 4t X20 I used beforehand.
