Overheating NICs in SuperMicro on FreeBSD

It could just be a problem with reporting, and not actually be that hot. I hope. Cuz 115 is melty time.
Most ICs should survive this. AMD had a range of GPUs reaching 95° - during regular use with no OC involved. But 115°C is a lot.
Broken sensors / reporting could be a reason, good point. @scottalanmiller: Got an infrared camera?

Onboard NICs? Strange
Yup, on board 10GigE. Getting more and more common these days.

Close but not quite. And we have several reasons to believe that it is really that hot. But false reporting is still a possibility.

It's not holding that temp, only spiking to it once a day or less.

Any correlation between network traffic and the temperature spikes? Does it happen at the same time every day, etc, etc?

Just talked to a friend who is much more into soldering etc than me. He said that 150°C is a temperature to look at, because the so-called https://en.wikipedia.org/wiki/Glass_transition might come into effect. As for the IC itself, there's a "https://en.wikipedia.org/wiki/Junction_temperature" to keep an eye on. Both are related more or less.

Yes, appears to be loosely related.

It was amazing that Scott found it so fast. I was on the Windows side of things. Inside Windows they were using the iSCSI initiator to connect to the FreeNAS. All the sudden Windows would just log a ton of iSCSI events and go down.
I looked up the events and most people resolved them by putting the iSCSI traffic on a separate NIC. This happened two days in a row at about the same time each day. I was looking at snapshot, backup, etc times when Scott found it in the FreeNAS logs.
