My MacBook (non-pro) Aluminum is a few years old. Lately I experience the problem that my fans are running high even with moderate usage and the body really heatens up.
It did this before, but only under heavy load (videos, flash or compiling of source files). Now it seems like a regular thing.
I also have the comparison to another MacBook Pro, which is definitely not showing this behaviour, so I am quite sure that I am not imagining things.
Also one night when I closed the lid of my macbook, fans would not stop running (it seems it did not go to sleep mode).
Any Ideas what might be the reason?
The only thing I can imagine is actually to open up the body and remove the dust from there with a spray duster.
