Occasionally, the airflow will be too low or, following the fads as of late, too warm, to be effective at cooling a high performance machine. More to the point, its great when your density per rack U is not that high to have warmer air or less air flow going. Web servers don’t generally run terribly hot. But start pushing GB/s through memories, through RAIDs, through networking cards … yeah, you start getting hot. Now add to this the nice high inlet temperatures … Less dense machines don’t care so much. More dense machines … they care. I can’t wait till people start putting GPU clusters into these rooms with 74+ degree ambients, and limited airflow. Ugh. High inlet temperatures coupled with low flow … just say no.
