    Yeah that was a broad statement for me to say it's ALWAYS running. So under my observation majority of the time I'm driving if I listen for it I can hear the fan running. At a red light stopped I can't hear it, but if there's one of those people in the lane next to me trying to floor it ahead of me when the light turns green solely because I'm in a Prius... well that fan speed ramps up smoothly as I accell, then slows down once I'm at whatever speed I level out at. Lol

    In my experience the fan does not run most of the time. I have an app on my phone to show various states of the car and only when the battery pack is hot it wil come on. As it is around 40F here, it never comes on. Even though at these temperatures I think it would be a good idea to force more heat onto the battery by using the fan to blow more interior air over the battery.

    I'm trying the Hybrid Assistant app in my car. It shows the temperature of the battery and also allows manual or automatic operation of the fan.
