High CPU usage.Thank you guys. Still even with SSD why Macbook Pro get's so hot since Macbook Air really dosn't.
Probably.(Or I have never pushed it to the limits?)
Depends on what sound and MBP, as there is the startup chime, the HDD access due to reading from it and on some older models the checking of the optical disk drive (ODD), if there is a medium inside it may need to read from.A bit of offtopic question - what is this hardware sound when you turn Macbook Pro on?

I have watched lot of unboxing videos and when they turn it on there is some kind of noise that Macbook Air dosn't have.
Something like this - http://youtu.be/ZrEE6Wy1Fmw
While the answer is in the comments, I will repeat it here.
It is the optical disk drive (ODD) checking itself for any inserted medium. If you insert a medium into the ODD, you will hear a similar sound, but newer MBPs don't make that sound anymore, due to a firmware upgrade I suppose.
My 2009 MBP does not make that sound, my 2008 MB and MBP did make that sound and my 2004 iBook did make that sound too.
On my late 2011 13" I still hear the optical disk drive noise on startup (original question) but not on lid open. Are you saying that the ODD should never make the noise due to firmware update?
