Mellanox ConnextX-2 10G NIC runs hot without airflow. I designed this mount so the card can be used in a single slot environment. To use this mount, you need to solder 2 wires to the 12V and GND test points. See photos to locate them on the PCB.The mount may interfere with the PCIE X16 clip. I removed it on my machine.For mounting you need some M2 screws.Lower right hole lining up with the hold in the PCB.1x M2*12mm1x M2 washer1x M2 nutUpper right: 1x M26mmLeft: 2x M23mmPLA will work, but it is recommended to use higher temp materials.
