My CPU goes to 156-158 after just a few minutes of AOE3 ... is that hot or wat,, i can scramble some eggs on that CPU
That's about 70C (idles at around 40 - 45C, such as browsing), which is normal temperature (when running graphic intensive 3-D games) for C2D to run on most notebook computers. It's counterpart on the desktop may run cooler given a more robust cooling environment, but running your stated temperature shouldn't pose any stability issues.
I've run C2s at as high as 80C without any issues.
If you're interested in keeping the cpu cooler,you can download a fan utility to keep your fan on maximum rpm.
Best of luck!
