That's one reason, but I'll list them all:
1: Short lifespan due to dirt/debris and environment.
2: Added wiring complexity.
3: Shorter runtime and more weight (albeit not much).
4: Poor subsitute for a proper motor/ESC. If things get hot where you need a fan to remain operational, chances are there is something wrong with the setup (needs larger motor and/or ESC, or different gearing).
5: If you rely on the fan to keep temps in check, what happens when it fails and you don't realize it? 'Cause you
know it
will fail...
However, if you have a good setup that runs just warm under normal use, and just use fans for
extra cooling, that's ok I guess. I just like simple, and additional fans goes against that.
