Hi Tuc, We had what sounds like a similar problem to yours. Fortunately, the change to the fan speed offset solved the problem for us. Here are the details:
We have 3 PE R720 servers that were purchased in mid-2013. All of them have Intel X540/2P I350 rNDC 10 Gb/s NIC's in them. I'm guessing that is similar to what you have in your R720XD. Two of the servers have worked flawlessly for the past three years. However, one of them, even from the early days of use, would intermittently report the following error: The system board NDC PG voltage is outside of range. That would cause a reboot event, which was obviously a serious problem. The server was under warranty and the technician tried replaced both the NIC and the motherboard. We still got the same error and reboot problem. Eventually, the issue got elevated to a L3 technician at Dell and they advised us to set the "Fan speed offset" to the "Low Fan Speed Offset"" setting. We made that change to the problem server and its performance has been perfectly fine since then. I'm guessing that the fan speed change solved the NIC overheating problem. I'm sorry to hear that it doesn't seem to have solved your problem. I think that the iDRAC Settings-Thermal GUI offers the "High Fan Speed Offset", which runs the fans faster than the "Low Fan Speed Offset" setting. Did you try the "High Fan Speed Offset" setting to see if that corrects the problem?
