jtd, as a potential WORKAROUND, does the following terminal command help address the fan noise level:
sudo cpufreq-selector --cpu=0 --governor=powersave && sudo cpufreq-selector --cpu=1 --governor=powersave && sudo cpufreq-selector --cpu=2 --governor=powersave && sudo cpufreq-selector --cpu=3 --governor=powersave

As well, did this problem not occur in a release prior to 14.04?

Also, would the latest mainline kernel 3.19-rc6 change anything?

Title:
  [Toshiba Satellite P855-S5102] Fan too loud while CPU idle

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  On Windows 8.1, fan is NOT loud. On Ubuntu 14.04x64, fan is always too
  loud (30 minutes after boot and after). BIOS is already updated.
  Update: If battery power only, fan possibly quiet for more time.

  I was hoping it was my LCD cooling_device4, but that has current
  cooling state 100 even when fan is quiet.

  $ lspci | grep VGA
  00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)

  $ sudo pwmconfig
  # pwmconfig revision 6166 (2013-05-01)
  /usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed

  $ sudo fwts -r stdout fan

  Loading CPUs for 20 seconds to try and get fan speeds to change.
  Fan cooling_device0 current state did not change from value 0 while CPUs were busy.
  Fan cooling_device1 current state did not change from value 0 while CPUs were busy.
  Fan cooling_device2 current state did not change from value 0 while CPUs were busy.
  Fan cooling_device3 current state did not change from value 0 while CPUs were busy.
