Alrighty after fiddling around with overclocking my CPU i've finally found a setting that i will keep. It's not the fastest possible but according to some Guides i've read and my experience so far this seems to be very stable, while running very cool and my CPU Fan makes no noise at all. Seriously i have an External USB Drive which is also very silent and beats that Fan by far.
Long Story short check out my Results
. I'm very satisfied
