Not a question, but important: There are two different models of this card and digitec seems to be shipping them randomly (I'll contact them about it)! There is the XG-C100C model and XG-C100C V2 model. XG-C100C model is PCIe v3 x4 based on AQC107 chipset. It gets really hot! (around 85°C) XG-C100C V2 model is PCIe v4 x2 based on AQC113CS chipset. It doesn't get that hot (around 75°C). On both models I get around 9.90GBit/s using iperf3 (i.e. as expected).
