Hi!
I know this is not the first post about noisy fan problem on MacBooks, but I haven't found any working solution jet.
My MacBook Pro almost all the time runs very loud even if it is in "choose boot disk" mode. I checked Activity Monitor when fans are loud and when they are quiet, and there is no difference, also there is no activity on hard disk.
I also reinstalled OS X, changed thermopasta on CPU and GPU with no luck.
But the weirdest thing is that fans are running so fast even when temperature is very low - 37 degrees.
I feel that problem is in EFI level, this could be some EFI virus or smth like that.
Here is screen shot from Activity monitor when fans are at 2000rpm:
Here when 6000rpm:
