Compact passively-cooled systems find application in a wide variety of market segments including industrial automation, IoT gateways, digital signage, etc. These are meant to be deployed for 24x7 operation in challenging environmental conditions. Supermicro has a number of systems targeting this market under the Embedded/IoT category. Their SuperServer E100 product line makes use of motherboards in the 3.5" SBC form-factor. In particular, the E100-12T lineup makes use of embedded Tiger Lake-U SoCs to create powerful, yet compact and fanless systems. Todays review takes a look at the top-end of this line - the SYS-E100-12T-H based on the Intel Core i7-1185GRE embedded processor.
