Hi,
The best fix for this is a little program called fan control. Not SMC
fan control, just fan control.
What generally happens on any apple mac since 2006 or so is when a
certain program starts, the OS makes a guess as to how much work the
processor is going to need to do and adjusts the fan accordingly. It
doesn't go by temperature. In theory this sounds neat, but in practice
it can sometimes lead to the machine running too hot or too cool (the
fan not spinning down when it needs to).
Fan control is a very accessible way to fix this. You can set a
minimum and maximum threshold (so when the machine hits a certain
temp, the fan will spin down to base speed, and you can set the
maximum threshold when the fan will max itself out at 6000 rpm). In
this way, instead of by program use, you can monitor and control fan
speed automatically by temperature.
The program shows up in system preferences once installed, btw, and
everything is accessible, right down to the monitoring of the fans and
CPU temperatures.
Another good program, if you bootcamp, is called lubbos fan control.
Does the same thing but is a bit less elegant. In windows especially
my mac gets very very warm. Lubbos fixed that. The processor would
easily reach its maximum temperature of 221 f for a long period of
time if the processor usage was above 80 percent until the fan figured
itself out.
hope that helps somewhat

Occasionally, usually when I'm charging, my Macbook Air's fan goes into
hyper turbo mod and really starts blasting. When I've had occasion to close
the lid for something else, the fan doesn't kick back on when I start
again.
So a question about the hardware, does the unit cool off faster when it is
shut down, or when the fan is really pumping?
