I don't blame you.
Seems that the design of the case itself is the probelm with the over heating issue. Over time the solder itself can become too hot and eventually break down and bring on the ROD.
Best advice is to have the box in an open cool area where it can breath. Shoving it into a crowded entertainment center or on top of other hot equipment (hot air goes up not down) is the worst thing that you can do.
I have not seen any good press about the addon fan kits (to the back) so I wouldn't suggest that.
