I never did this on a laptop as all of mine where build in a way that
dust could not collect. So, it depends very much on the model.

I do this every year on my desktop. The temperature drops then by 10K.

You can use the CPU temperature as an indicator when a cleaning is
needed.

But blowing does not work on my machine. I really have to take screw
driver and tweezers to get the work finally done.
