I've got 3 servers based upon the S5520HC board in a 1U Chenbro case. Each has 2 Xeon E5620 CPUs cooled using Intel's passive he cooler. Problem: On full load with all fans on full speed the second CPU seems to get too much hot air from the first CPU. It gets too hot (>95C) and Linux starts complaining.
Obviously the coolers are not sufficient for this board. What would you suggest?
