MBP runs cooler on Lion..

WOW My 2011 MBP runs so much cooler with Lion!

While reading the forums having mail, skype, ichat, itunes and torrent it got to 37 degrees! Then when watching netflix it didnt past 75! The fans are running on default average at 2500RPM...

This is super awesome since this thing could toast my man parts while using it in my lap..

My MBP 2011 i7 is about the same. Personally I do not think Lion is CPU heavier on Kernel jobs.
It is a bit more memory hungry but that should not make your MBP running hotter.
