Before I had the same problem with motherboard which reported Platform ID as S2600SDP
Intel has replaced motherboard to me by standard warranty as wrong motherboard
New board has correct identification. And Power Supply FAN was working quietly.
Support person recommended me to upgrade BIOS on new received board and the story has repeated.
Power Supply fan rotates at max speed.
It is not PS Fan fault. It is some other fault.
As I know already, the loud PS Fan is made for signalling of critical system faults.Customer support by phone replies too slow.
So I decided to ask here.
Please, help me identify the fault source. ( taking into account that fault raised right after BIOS UPGRADE )
I attach sysinfo logfiles here
Thank you.
