    My 2.66ghz MacPro (2007), on occasion hear a wincing noise coming from the top rear of the machine. sounds like almost like HDD spin a very kind of whispery spin (not the seeking sound) almost more a spinning sound similar to a case fan.

    im just alittle nervous because my surge protector was accidentally shut off a few weeks ago while my system was on and i ran Hardware tests to test any of the hardware and it has remained up and running since then. im wondering if this a normal sound, its not a consistant noise/sound but i hear it ever so often.


    any info/advice would be appreciated! thanks!

    bump ~ noone else notice this before or am i the only one?

    how hard will it be to have a PSU replaced? even if its the case, which im not sure if it is or not. my macpro is raise about 12" from the ground on a non-conductive platform off the carpet an di can hear it occassionally and i can tell its the PSU noise because when i put it to sleep i hear it click off.

    i just wanted to know if this is normal behavior or not.
    and any suggestions.

    thanks!!
