My reasoning was that: in order to move the amount of air that a PC fan is designed to move, it moves at the RPM it is designed to operate at. It is designed to spin at that RPM for a reasonable lifetime (number of revolutions). If you accelerate the RPM of the device x1000 by blowing an air compressor directly into the fan, it stands to reason that you are exceeding the RPM it is designed to operate at, as well as "adding years to its life" by burning through a bazillion of the revolutions the manufacturer designed it to complete before failure.
Therefore, if using an air compressor to blow out a PC, stick a pencil or something in the fan to hold it in place so you don't wear out the device unnecessarily. Maybe you can use a more correct mechanical terminology to describe why that is.
