CPU is 70 C and fan in lower left corner is noisy
The fan in the left hand corner of my iMac is very noisy almost as soon as I boot up, and stays noisy all of the time. The temperature of the CPU is around 79 degrees Centigrade. I think that's very hot, as the limit is 85. Could it be that the CPU fan isn't working properly? Should I lubricate it/clean it?
Is this a good question?
