Intel system boards conta n a number of h gh-dens ty VLSI and power del very components that
need adequate a rflow to cool. Intel’s own chass s are des gned and tested to meet the
ntended thermal requ rements of these components when the fully ntegrated system s used. It
s the respons b l ty of the system ntegrator that chooses not to use Intel developed system
bu ld ng blocks to consult vendor datasheets and operat ng parameters to determ ne the
amount of a r flow requ red for the r spec f c appl cat on and env ronmental cond t ons. Intel
