Title:
  CPU fan speed regression since 15.04

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  When running 14.04 my CPU fan speed increases relative to the CPU
  temperature, which keeps the temperature fairly constant.

  When running 15.04 or 15.10 the CPU fan speed is locked to the minimum
  until the temperature reaches 81 degrees, then it switches to maximum
  until the temperature falls below 72 degrees. Then it goes back to the
  minimum. This is both annoying and causes unnecessary stress to the
  hardware.
