How to fix temperature threshold CPU throttled errors? [closed]

edit

Ok,

Fedora 19 has caused nothing but problems;

I have a desktop with an AMD 7750 Graphics card which since upgrade fails to load gnome at all, tried akmod kmod, direct drivers nothing ... (there's a separate question here I'm following on this issue).

But the focus of this question is infact an i5 laptop, which never having had a problem with 18, since upgrading is constantly throttling the cpu:

[26670.911219] CPU1: Core temperature above threshold, cpu clock throttled (total events = 1)
[26670.911221] CPU0: Core temperature above threshold, cpu clock throttled (total events = 1)
[26670.911222] CPU2: Package temperature above threshold, cpu clock throttled (total events = 1)
[26670.911223] CPU3: Package temperature above threshold, cpu clock throttled (total events = 1)
[26670.911224] CPU0: Package temperature above threshold, cpu clock throttled (total events = 1)
[26670.911232] CPU1: Package temperature above threshold, cpu clock throttled (total events = 1)
[26670.912202] CPU1: Core temperature/speed normal
[26670.912204] CPU2: Package temperature/speed normal
[26670.912204] CPU3: Package temperature/speed normal
[26670.912209] CPU0: Core temperature/speed normal
[26670.912209] CPU1: Package temperature/speed normal
[26670.912212] CPU0: Package temperature/speed normal

The cpu in question: Intel(R) Core(TM) i5-2450M CPU @ 2.50GHz

Even stranger is on inpsection of /proc/cpuinfo the 4 notes cores are all running at differnt cpu Mhz ...

cat /proc/cpuinfo | grep MHz
cpu MHz     : 1800.000
cpu MHz     : 1025.000
cpu MHz     : 1475.000
cpu MHz     : 2350.000
cat /proc/cpuinfo | grep MHz
cpu MHz     : 1825.000
cpu MHz     : 2600.000
cpu MHz     : 3025.000
cpu MHz     : 2825.000

Seems to me that the CPU scaling is miss behaving; any suggestions as to a remedy?
