Pro: There are good fans turning quietly even when you get up to speed, you are still pleasant to listen so you do not disturb. The bearings are solid can not scratch him before coming what one of my old CPU fan can no longer claim because the camp does make noise when it comes turns on its 15 hundred and if you move it with your hand you can hear it clearly, what with the new fan is not the case.
Cons: The only thing bothering micht is what could be improved in the future as I'm on a small extra charge which is one in the harness again drumstülp a Schutzumantel, tuned and glued or off bresst.
