i have a mac 512ke that has a cooling fan on top when the computer runs for a bit it starts making the ringing noise and if i cover the hole where the fan blows air out i dont hear the noise. |

Perhaps try dismantling and adding a drop of oil to the fan bearing. Only a small amount needed, the bearing is often accessible under a sticker on the fan hub. |
