Free Cooling: the Server Side of the Storyby Johan De Gelas on February 11, 2014 7:00 AM EST
Since Supermicro claims that these servers are capable of operating at inlet temperatures of 47°C (117 °F) while supporting Xeons with 135 W TDPs, we tested with two extreme processors. First off is the Xeon E5 2650L at 1.8GHz with a low 70W TDP and a very low Tcase of 65°C. It's low power but is highly sensitive to high temperatures. Second, we tested with the fastest Xeon E5 available: the Xeon E5 2697 v2. The TDP is 130W for 12 cores at 2.7GHz and Tcase is 86°C. This is a CPU that needs a lot of power but it's also resistant to high temperatures.
