Overheated Macs?

Hey,
I have MacBook Pro (released at the second half of 2009) that has two graphics card.
I installed iSTAT Nano widget to monitor the system, please take a look at the attached screen shot.
My MBP is really becoming hot, especially the left side and the bottom piece.
Regularly, the "GPU Diode" temperature is reaching 70 !!
Is this normal for MBPs? or it is just mine?
I'm really anxious of possible potential problems.

I'm curious whether you found anything out about this.

I did some searching, and found a lot of forum posts reporting GPU diode temps in the 60-80 C range -- typically while gaming. However, I don't know if that means it's "normal" or whether it's simply a common issue. I found a lot of conjecture [citation needed ], but nothing conclusive.

I have an i7 MBP running about 14 applications:

2 browsers
IDEA
Tomcat
MySQL
Excel
TextMate
Terminal
Adium
Skype
Mail.app
Pandora AIR app
Preview (PDF)

Bottom left is really hot, but as I understand it, the case is part of the heat-sync. The case itself is used to dissipate heat away from the system. So it makes sense that it is hot.

It looks these numbers are usual and nothing to be afraid of.
According to "Apple Discussion Forums", a Mac will turn itself off when it is over heated.
 
It is sorta covered in the JavaRanch Style Guide.
