The middle fan on my H150i Pro makes this buzzing / crackling noise and starts to appear only when its above 1450RPM. Other 2 fans are quiet even at 1600RPM. I know its only this middle fan making the noise because I managed to pinpoint it through iCue software by fiddling with each fan's RPM. I tried to loosen and tighten the screws but the noise is still very audible and is annoying. I think the fan's motor making this sound but I'm not sure. Any ideas or help is much appreciated. PS:This suddenly started to happen after 4months of usage. [ame] [/ame]
