I am looking for information from people with systems with Supermicro motherboards with a Broadcom 10Gb NIC controller chip (BCM57416). Specifically, I would like to find out the NIC temperature IPMI reports on your board (for example, running "ipmitool sensor" or the IPMICFG tool "IPMICFG -sdr"). We have such a system, with the X13DAI-T board, and IPMI reports a NIC temperature of 71C-74C. This seems extremely high -- likely to damage the chip and the board. Other systems, with onboard 10Gb Intel NIC controllers, report temperatures around 45C. Thanks!

Thanks for the reply. I could not find temperature specs for this chip on the Broadcom website. However, for the Intel X550 controller Intel specifies a maximum operating temperature of 55C (Intel® Ethernet Controller X550-AT Product Specifications). Note that this chip is quite old (2016). We have some motherboards with this chip and IPMI reports around 45C for them.
Thanks again! I found the datasheet you are referring to. I hope your interpretation is correct. On the page I specified earlier, where they specify "maximum operating temperature" of 55C, they have an explanation that this is "the maximum operating temperature allowed as reported by temperature sensors" -- I interpreted that to mean that this is the sensor information that IPMI is able to retrieve. Hopefully, my interpretation was wrong. One thing for sure -- in the future I'll try to only purchase motherboards with Intel controllers.
There are further pages that explain that it's ambient operating temperature, but it's 1200+ page datasheet, so who wants to go through that. Broadcom is fine too and you should be fine with that over Intel. I haven't looked through their datasheets, but operating conditions should be similar.
