But I never have to mess with the fans off silent even while running heaviest anything ;-) also planning on upgrading next year so this will have the headroom for max OC/sli/xfire and never have to adjust the fans off silent.
So going through the trouble/expense of adding 24 fans to the system for no gain added noise when I had other things to spend money on ..well.
