Yes those temps are pretty warm...and maybe the highest temps I've seen (which probably explains why your Mac is shutting off). The highest temps I have seen previously have been in the 90C+ range.

Like you said..this problem only occurs when you're running Windows 7...and you're probably pushing the CPU & GPU to it's limits playing the games you mentioned.

Things you could try to reduce the temp:

1. Don't use the laptop on your lap. The heat from your body & the reduced ventilation will make your laptop run hotter.

2. Place your laptop on a hard-flat surface with good ventilation to help reduce it's temp while computing.

3. You could place a fan close to your computer. Extra cooling air passing by your laptop may help.

4. Believe it or not...the temperature of the room you are in can play a part in how hot your computer gets. A 90F room without air-conditioning will make your laptop run hotter that an 80F air-conditioned room...or even a 65F room in the Wintertime. So use your computer in the coolest room in your home.

5. Lastly. For Macintosh computers there's a program called "SMC Fan Control". It tells you the temp of your Mac, the speed of your Mac's internal cooling fans, and allows you to adjust your fan speed. But...I'm going to guess with your Mac running as hot as it is...your fans are probably already running at their maximum speed.

Also...I'm not sure if you're running Windows 7 via Bootcamp or via Parallels/VMware Fusion. If you're using Parallels/VMware Fusion....then you can use "SMC Fan Control":

Download smcFanControl for Mac - Control Intel Mac fans to make it run cooler. MacUpdate Mac Software Downloads

...but if you are using Windows 7 via Bootcamp...you may need to find a program similar to SMC Fan Control for Windows computers.

I hope that this helps,
