I just bought a Macbook Pro 13" with the i7 processor and was doing a battery calibration for the first time. So I decided to play some Starcraft 2 (medium settings) to help drain the battery faster. After playing for about 5 minutes, I hear the fan turn on. After about another 5 minutes, I used my iStat nano widget to check the fan exhaust speeds as well as the temperatures. I saw the temperature was at 91! The fan speed was peaking at 6200 rpms. I have searched all over the net but have failed to reach any explanations. Can someone please tell me if this is normal? My macbook did not shut down btw. Any help would be greatly appreciated!!
