Hi all, When I first built my current rig I thought that it was really quiet. However, since then I've been bothered by the noise it emits at idle. I have all fans powered down to minimum. What else can I do to lessen the noise output of this computer? The Antec 1200 is using all stock fans and my H80 is using Corsair fans in a push pull configuration. The case is also 3 years old if that matters. Thanks in advance.
