Hello,

I have an X10Dri-t board which has a couple of Intel X540-AT2 NIC's. If nothing is plugged into the NIC the idle temperature is 55C (reported using ipmitool sdr). However, with cables into the NIC the temperature rises 83C, and with load in 90's. The motherboard starts registering health warnings.

Anybody aware of such problem with Supermicro boards?

Thanks

What is your airflow like over the NIC heatsink? If you have it in a desktop chassis with a large GPU over it, I'm not too surprised.

Pretty normal for all but the newest 10G chipsets for copper, one reason that SFP+ is preferred by many. Have to get some airflow over the heatsink.

It is a SC846 chassis and there is a P2000 GPU over it. The airflow isnt that great the chassis fans. But i have put a 120mm fan sitting on the PCIe cards and blowing air down.

Any idea about the temperature limit of the NIC?

No temps in ARK only the inlet temp which seems high at 55 degrees.
So I don’t know the answer to max temp but maybe 90-100 is not unexpected as max temp

Just started seeing the same issue on my X10Dri-t board and found this post!

This is what needs extra cooling:

UPDATE: I super glued a Noctua NF-A4x10 FLX fan directly onto the heatsink and connected it to one of the 4-pin fan headers right next to it.
Problem solved, and silence maintained. Temps now at a respectable 69 degrees C under load.

Are you not using the PCIE slots next to the heatsink? With the fan in place a card will not fit over the heatsink.



I have an SFP+ card sitting over the heatsink. Wonder what is the best way to get a fan close to the heat sink.



A picture of your fan+heatsink setup would be nice :)
