I have these fans concerned as front fan for my Graphite 600T, in which he blows air. And yes - it blows tidy! ;) Attached to it is the integrated fan controller. In 9-clock position he is practically inaudible, only when I turn up to 3/4 one hears a (discreet) air noise. In case a decent draft is then to feel, all the components are well chilled. The temperature of the CPU and GPU have been reduced under load by 5 ° C or 6 ° C (had previously inside the standard fan of Corsair, but which was unbearably loud). All in all a really good fan!
