Not router or flash memory but I had experience of set top boxes 
overheating and becoming unreliable usually because the feet they fit to 
the boxes only allows a few millimetres of air to circulate under the 
box. I've often fitted taller feet and/or put the boxes on a a couple of 
pieces of 2"x1" timber to increase the air flow beneath the box. Also I 
don't stack one box on top of another that may be generating heat nor 
operate the boxes in an enclosed cabinet.
