I happen to have the Late 2007 MacBook Pro. When I use it with Firefox, Safari and iTunes, it averages between 57-61C. When I check the GPU temp, it tend to go close to 70C+ but the heatsink temp stays between 60C-70C. The fans spin between 1998-300+ rpm. Is this normal?
Also, just how much of a temperature load takes place when I connect it to an external LCD monitor or LCD TV? I just got the iLap and it does make a difference. Also, when I connect the battery for recharge and use it, the temperature shoots up and the fan speed touch the 3000+rpm range. When I remove it, it runs cooler.
What do you think is the stable range for the GPU diode and the heatsink temperature when running?
