[ Disclaimer: I work for a 'white box' cluster vendor called Western 
Scientific. ]

There are no specific heating problems w/ Opteron Series 200, even the 250 
model.  The problem this vendor might be having is w/ the temperature of 
the processor closest to the i/o ports on the motherboard.  In poorly 
designed server enclosures there are significant temperature differences 
between the two processors.

Heat dissipation problems have also been seen by customers using certain 
vendors products who have too dense of a server solution with out 
sufficient processor cooling (either blade or 1U... especially with 4 
processor motherboards).

If you would like to discuss this potential problem in further detail 
please contact me off list.
