It really is a little sad that they've made it this difficult to control 
the temperature of your systems.  I'm sure I'm not the only one who has 
a box in an area without summer climate control where it is gonna get 
hot and humid.  For now, the combination of FanControl and Mouse Jiggler 
is working nicely and I'm going to leave it alone and continue monitoring.
