Not exactly correct. You can spin the fan blades fast enough with the
can-o-air to have them disengage. I know, done it. They aren't designed to
turn at the kind of rpm one can subject them to with a stream of air. Flying
shards of plastic and hurt and of course poke you in the eye. Sure it sounds
neat and looks cool to see that thing spin like that, but why ruin it?
Compressed gasses can be really harmful. I've also blown apart a wheel
bearing from a truck doing the same thing drying solvent. Scary to have all
those steel rollers ripping by. Yikes!

Be careful, but DO clean your fans, Q-tips are a great suggestion then a
quick blast to move the dirt out.

Unplug the computer. Remove the case. Touch the case frame to  avoid
static problems.
Try to work your way from top to bottom, blowing the accumulated debris
out of the case. There's nothing you can hurt with compressed air. Pay
special to fans and fan blades. I have found it necessary sometimes to
use Q Tips to clean fan blades. I also blow inside USB and other ports.
In bad cases, I remove all the wires and take the computer outside, then
blast everything I can see with canned air. I have a vacuum, but it's
not good for much. Too slow and not enough suction.
Your computer will thank you.
