if the humming is too loud, wouldn't it just be better to get newer 
and quieter power supply and case fans than risk the heat? i've got 3 
case fans in mine and not much noise at all. and that's not counting 
the cpu fan and a fan on a swappable drive unit. old fans make noise. 
get something newer and smoother running.
