Why are the fans running at full speed?
The fans on my 17" Macbook Pro are running at full speed regardless of the temperature of the computer. Even if I turn on the computer when it is stone cold the fans almost immediately start racing.
When I look at the CPU temperature sensor I see massive fluctuations in the readings. Within a 5 second timeframe the temperature will jump from 210 to 180 to 196 then back to something in the 200s.
Is this a good question?
