Cricket Sound and Excessive Fan Noise

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?
