Fans Of Fans
Many of today's rack servers include removable air ducts to maximize air flow over processors, memory and other heat-generating components. Dell adds extra utility to its shrouds by labeling them where appropriate to help simplify memory placement. The R720's six fans can be removed as a single unit or individually without the need to power down the server.
What's more, the underside of the R720's cover is home to helpful servicing information, including motherboard layout, memory population diagram, jumper settings and component installation and removal. To compensate for loss of airflow, fans speed up when the cover is removed. Otherwise the R720 remains quiet as a whisper.
