   In that case, does it get enough airflow inside the case for its   
   cooling needs?  A clogged PSU fan, reducing airflow through the box in   
   total, would also reduce airflow for the fanless card.

   Your other post about switching to a node.js application from your own   
   C code implies that this switch might be the cause.
