The fans on my Mac Pro have developed a mind of their own no matter how many times I reset the SMC and/or PRAM. These things only provide temporary relief at best. I am also getting "no wake from sleep and kernel panics on startup.
The fans sound like a motor race. Any activity, however small starts them accelerating. They usually, but not always slow back down. The air coming out of the back is pretty cool, as is the ambient temperature here.
I am hoping this is not because my Mac Pro is an early 2009 machine with a "professional" 12-core processor upgrade. It has been working fine but not really since OS 10.8 and it really lost the plot when I installed iTunes 11.1.
Has anyone else experienced this?
