I recently upgraded from a Neo 1 to the 2T. Once the unit is activated by moving the pedals, there is a ticking sound (like crickets) coming from the back. In addition, it seems like the fan is not properly calibrated as it speeds up excessively at cadences above 80 rpm. If I pedal at lower cadences, the fan normalizes. Right now, the 2R sound louder than the Neo 1. Is there a firmware update in the works to address this issue?
