Hi,
I have mid 2010 iMac. I noticed when I use high brightness to some noise. what I hear is very weak (I notice the noise only when I'm working on a computer at night). Noise is a low beeeee (not Buzzzzz). It is important to emphasize that the beeeeee noise also disappears when the brightness is also on maximum
This is normal?
