I too have a AMD phenom processor.
I too posted a query regarding the noise.
Finally i changed the Fan mode from AUTO to PWM.
By doing so when i iam watching movies,listening songs copy paste etc smalll things the CPU is quiet enough.
When iam gaming it is loud but not too loud and running at ~5k rpm.
And by changing mode there is a lot of difference try it.
