We had a supplier that liked to avoid putting the guards on the fans.

It's generally not a good thing ...  there is injury risk as well other 
issues (possible electrical shorts for cut wires, fan self destruction 
due to impacts ... and subsequent shrapnel ...)

Whenever possible, we like to try to route wires away from the fans, or 
if we have no choice due to length constraints, we will try to tie them 
to rigid structures to prevent interference.
