Temperatures

Does anyone else see Fedora running hotter than Ubuntu? I'm running Ubuntu 14.04 (obviously pre-release at this point) and Fedora 20 with their current (12-Apr) 64-bit kernels, and I see:

Code:

Ubuntu 1404

~$ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1:        +47.0°C  (crit = +106.0°C)
temp2:        +29.8°C  (crit = +106.0°C)

coretemp-isa-0000
Adapter: ISA adapter
Physical id 0:  +50.0°C  (high = +87.0°C, crit = +105.0°C)
Core 0:         +50.0°C  (high = +87.0°C, crit = +105.0°C)
Core 1:         +44.0°C  (high = +87.0°C, crit = +105.0°C)
=======================================================================
Fedora 20

~$ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1:        +63.0°C  (crit = +106.0°C)
temp2:        +29.8°C  (crit = +106.0°C)

coretemp-isa-0000
Adapter: ISA adapter
Physical id 0:  +64.0°C  (high = +87.0°C, crit = +105.0°C)
Core 0:         +64.0°C  (high = +87.0°C, crit = +105.0°C)
Core 1:         +60.0°C  (high = +87.0°C, crit = +105.0°C)

Would like to bring the Fedora temps down, but don't know how to change the cpu frequency governor in F20. F20 runs at 2.5GHz constantly vs. 1.0GHz for Ubuntu when (more or less) idling.

Advice greatly appreciated.

have you left you computer running for some time so that temperature become constant?

Yes, I have. I suspect getting the Fedora kernel to use the on-demand frequency governor might do the trick, I just don't know how to change governors in Fedora

I think Ubuntu does not give a true value. The outside temperature 27celsius.

$ sensors
radeon-pci-0008
Adapter: PCI adapter
temp1: +0.0°C (crit = +120.0°C, hyst = +90.0°C)

k10temp-pci-00c3
Adapter: PCI adapter
temp1: +1.0°C (high = +70.0°C)
(crit = +80.0°C, hyst = +79.0°C)
