fires? I've only heard of the one burnt component ie flash/smoke is all....anyway just heard of the 1 board issue I think?
with a metal case and the cover on away from clutter I'd suspect most of us will be fine imho..now a case less/open unit not so sure?
Searing
Wouldn't an open case be better for heat if not also airflow? I think I should open my case and put a big fan running on it
Something like this maybe?

I did notice better performance boost.
However I am going to swap out the stock fans on the case and instead put in higher CFM fans.
