    My Mac Pro 8 Core 2 x 2.8 GHz Quad-Core Intel Xeon with Leopard 10.5.8 started making a humming noise about a month ago. The humming noise is very consistent in pitch and is always humming whenever the computer is on, except for when sleeping. Any thoughts?????

    more than likely hard drive(s), causing a vibration,
    mine was the same, a low pitch humming noise, both me and a friend that was also getting this noise,(both mac pro's were on hard surfaces) cured it by finding an old foam mouse mat and cut it up, placing it under the legs, no more noise :)
