OnLogic Karbon 700: Passively-Cooled, Up To 8 Core / 16 Thread Industrial & Rugged PC

Like the Karbon 300, the Karbon 700 has been working out very well still after weeks of continuous load/benchmarking. Even with the more powerful components, the Karbon 700 still operated fine on passive cooling and is built incredibly rugged.

The Karbon 700 is in a class of industrial PCs similar to the CompuLab Airtop 3 but with the OnLogic PC having more connectivity and smaller. The Airtop 3 we have in our labs is slightly faster with having a Xeon E-2288G processor and NVIDIA Quadro RTX 4000 graphics, but interestingly the Karbon 700 did operate much cooler than the Airtop 3 PC.

Over the course of running the same workloads between the Karbon 700 and Airtop 3 (among others) for several hours, the Karbon 700 was operating much cooler:

Under a wide range of workloads, the Karbon 700 had an average core temperature of just 51 degrees (Celsius) and a peak of 80 degrees and an idle temperature of 27 degrees. In comparison, the Airtop 3 with its slightly faster Xeon CPU (as well as having to passively cool the RTX 4000 graphics) had an average core temperature of 68 degrees. All of the other industrial PCs tested besides the Karbon 700 all peaked into the 90s under demanding multi-threaded workloads. So from a thermal perspective even with our review sample configuration being at the upper-end of the Karbon 700 configurations, the cooling performance was great out of the Karbon 700.

The Karbon 700 arrived with Ubuntu 18.04 LTS (OnLogic also offer options of Windows 10 and Windows 10 IoT Enterprise) while for this benchmarking comparison we upgraded to Ubuntu 19.10 for the newest Linux packages.
