how to update intel PAC(arria 10) BMC
- 4 years ago
Hi Penghui,
Thanks for contacting Intel support.
Please go through the thermal guidelines which would help you to get more clarity on thermal usage of the PAC.

Regarding reducing the noise and about adding extra fan , I think a detailed analysis might be required.
Thanks and Regards
Anil
It took me a week to track down the issue: the motherboard's pcie3 x 16 slots on the second cpu does not work with pac, had to move to 2nd video card slot on first cpu to make it work: ( it is previous version of firmware 1.1

now, I just have to solve the temperature issue, had to turn on high speed fan ( 40% ), it is quiet noisy, temperature still on the high end ( start with 53C and level off on 58C ). Hopefully add extra fan would help out and I don't have to go the water cool solution.
