My MacBook Pro (purchased in December) gets extremely hot on the bottom.  I downloaded a program called istat and when I checked the stats for my computer, the cpu was at 171F!  Is that normal?  All I was doing was checking my friends Facebook statuses...  I had noticed it seemed pretty hot and whe I searched for answers, came across the suggestion for istat in the desktop community...  Any ideas?

MacBook Pro, Mac OS X (10.7.3)

    Check the Apple article below.

    It will shut down automatically if it gets too hot. What speed were the fans? Were the vents clear? Was anything else running (istat will list the top processes too)?

    171F == 77C? Quite within the operating range of these computers. I've run mine close to 99C when using virtualization software. If you've never owned a metal-cased portable before, note that it is quite a different equation than a plastic one; the case is used as a heatsink and is supposed to get warm. Also, these are not meant to be considered laptops, they're portable high-power computers.

     

    If you want to keep it cool, may I suggest you invest in a cooling stand or pad to place underneath while on the desk or table? That will raise the Mac and let air circulate underneath. Can get passive stands that just raise the computer, or stands with fans for more cooling. http://laptopventilation.com/

    You can also download smcFanControl on sourceforge and manually control the temperature on your MacBook Pro like I've been doing. When you find it's getting hot for your fingers or your lap, increasing the fan speed to about 4000 RPM makes a big difference. You can go a little higher too.
