Is that why maybe I can hear the PC at 12V?
Well at least that's my reasoning.
Anything under 12v is ok on the metal grills, however a af140 doesn't have that problem.
The reason why, in my opinion is because there is no spacing in between the fan and the grill on the fractals.
Whereas with the af120s for example there is an extra rubber material in between.
