    The fans in my Mac Pro are apparently in Blitzkrieg Mode right now, and I have no idea why. They are as loud as they are in a firmware update. The only thing unusual is that I moved the computer to a different room several hours ago. Please advise.

    SMC prolly got confused... it happens.

    Reset SMC by unplugging the power cord, waits um, about 5 minutes is more than enough. Plug the power cord back in.

    Should be fine. There is a switch inside on the logic board called SMC Reset. Could do that instead but this way keeps you from having to pop the side off.

    Good luck - I'm pretty sure this will take care of it.

    I'll try this unplugging for a few minutes.

    Gotta ask. What is SMC? :eek:

    System Management Controller controls all kinds of temp control and power management stuff... here's a link to the Apple site of what you're doing here with the SMC reset:

    Seems to have worked. I unplugged it and went to dinner, came back and turned it on. Thanks for the help. :apple:

    Not saying the wood ducks are bad but I think the rest of the pictures are phenomenal. Great work

    To reset SMC quicker, just unplug the powercord and hold down the power button for 15 seconds.

    You can also try resetting PRAM.
