OK we have a h8DCE 2 socket opty board and the problem is that one of the sockets overheats.
There's nothing wrong with the cooler (active) as this has been swapped out with the other socket.
There's nothing wrong with the CPU as this has been swapped out with the other socket.
You boot the board and after 2mins or so you get the temperature alarm. If you look in BIOS as soon as you boot you can see CPU1 is at 38C and CPU2 starts out at about that but the temperature rises steadily untill the alarm goes off and we shut down the board.
The voltages reported in "system health check" are stable and equal for both sockets.
Any ideas people?
I should say the PSU cooked off prior and was replaced so *that* may have caused some damage... but I don't understand how the temperature of the CPU can rise continually at a constant voltage and with exactly the same cooling as the CPU next to it which is fine!!??
now your first thought maybe that there isn't a good contact with the heatsink.. There definately is, tried reseating it, replaceing it with the one from the other socket etc. The heatsink is solid as a rock on the chip, screwed in nice and tight.
