The fan cooled reliably and runs almost inaudibly.
But because I was clear that not the case fans run alone to success. After installation I have unfortunately still hear the fan of the CPU / Mainboads, in such a way that it has annoyed me in the long run so (I'm sitting right next to it) that I equal to a new computer in Anchorman in the configuration Be quiet! bought.
My verdict - the fan housing alone does not make a "be quiet" computer
Conclusion - not cheap, but quality and performance technically all worth the money.
