idle its nearly silent, full gaming load will be louder. depends on components.
I Think I will go with the amd fx-6300 with the stock heatsink, but later on I'm thinking to upgrade on the noctua nh-d14. A little side question, will my cpu oc to 4ghz or even 4,5 with the noctua? and with those settings can I still use the low noise adapters? And as my video card I will buy the evga gtx 660 superclocked. Or is there a much difference to the asus gtx 660 direct cu II ? It says its 20% cooler and 3x quieter but idk. And my psu will be seasonic M12II 520w. I suppose It's a fairly silent psu, many people say that.
