Title:
CPU fan speed regression since 15.04
Status in linux package in Ubuntu:
Confirmed
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.
