| A few things will make a difference;
how is the air circulating around the Mac? If it's in a corner where it can't circulate freely, it will be more hot, and run louder. Also ambient temperature will make a difference on that, and other differences are what applications are running, how much ambient noise is on etc (there is a difference between 5 and 35 dB...)

Twenty years from now you will be more disappointed by the things that you didn't do than by the ones you did do.
