Hi all,
I just bought a 15" MBP with i7 dual core processor and an accompanying Cinema Display and was planning on using this combo to as my desktop setup. I also have iStatMenus to monitor CPU heat, fan RPMs, etc. When I use my MBP without the Cinema Display iStatMenus shows an average CPU temp. of about 48 deg. Celsius and fan RPMs of just under 2,000 for the two fans. However, when I close the MBP (clamshell mode) and hook it up to the Cinema Display, the heat goes up to around 65 deg. Celsius and fans run around 4,800 RPMs on average.
