I have this curious thing happening ever so often , when i wake up the mac pro. The fan will run at the highest speed possible for about 20 seconds and then slowly decelerate. I reset it, but turning off-unplugging the power-and pushing power button. I also upgraded the firmware to 2.1, hoping that would change it. But it still does it ever so often. Wonder what that is all about. My other mac pro (also with 2.1 firmware) only did that once and resetting it worked.
Any idea what could cause it?
