dell poweredge sc400 previous shutdown due to thermal event

Archived from groups: alt.sys.pc-clone.dell (More info?)

FYI and a question at the end.

After installing a new dvd drive into my dell poweredge sc400, the pc failed
to boot. It was dead apart from the power switch which was flashing amber.
No fans or HDDs spun, the 4 diagnostic LEDs on the back were dead too and
there was no warning beeps. It was dead.

All indications pointed to a faulty power supply or motherboard - yikes! I
swaped in a new power supply I had lying around but the same fault
persisted.

I might point out that whilst I was rebooting, I was measuring 5VDC from one
of the motherboard/power supply connector pins. Even with the power cable
disconnected that 5VDC stayed there for some time and only went away after
pressing the start button on the front. In the back of my mind I was
thinking that if I managed to remove all voltage I might kick the m/b back
to life somehow. During this time I also reset the CMOS memory.

To cut a long story about cable swapping short, it wasn't until I removed my
sound and video cards that the computer sprang to life! Yippee! After this,
it booted every time.

AND NOW MY QUESTION....
During the 3rd reboot the computer powered down by itself (ungracefully I
might add). When I rebooted I got the message:

"the previous shutdown was due to a thermal event, press f1 to continue
or f2 to setup"

My fans are running and I suspect this might be a glitch? Is there a way to
quick measure the temperature of the offending component?

Cheers,

Peter

    The "thermal event" pre-POST message points almost exclusively to either CPU
    or CPU socket/mb failure.

    In most instances I've seen, it was simply due to CPU overheating due to a
    failed chassis fan, etc.

    sc400 or 400sc? i only know of a sc420, sc430 and sc1420 so i assume you are
    talking about a 400sc. if so read on...
    the poweredge 400sc has a garnered a reputation for random reboots and blue
    screen of death due to leaky capacitors near the processor socket. look on
    your motherboard to see if any of the capacitors are leaking or bulging at
    the top and then talk to dell about getting it replaced. here is a thread
    from dell's forums about it... search google for many more...

    Chris -

    Isn't the 400SC the PE version of the Dimension 8300? (Intel 875 with
    different plastics and a couple other minor mods)?

    I'd not known those to have cap problems on the board, but perhaps as a
    'server' that might be different....

    that is right. perhaps they just happened to use some inferior capacitors
    on a batch of the pe motherboards. it doesn't seem to have happened to all
    of them, but too many of them for dell to ignore. there have been reports
    of out of warranty replacements offered by dell to customers with failed
    boards. here is another forum site that has a relevant thread on the
    subject... great resource for other poweredge related questions/answers...
