Windows 10 - Toshiba Satellite e55 running hot

In Win8 I watched my temps closely and was usually around 38 to 44 c under a normal load.  However since upgrading to Win10 I noticed my normal idle temps were around +45c.  Even if the computer was untouched for several minutes and the task manager said CPU usage was below 5% the CPU temps would remain high and the CPU frequency would remain high.

After installing some Toshiba drivers and switching the battery / power mode to the Toshiba's "eco" mode the temps and CPU frequency dropped immediately.  As I make this post my CPU ghz is at .78 and my temp is 40c.  Before changing to Eco the CPU mhz were constantly around 1.3+ ghz even at idle.  So even when the CPU was doing nothing Windows 10 was not scaling down the CPU freq the way it should.
