SUMMARY: Temperature woes?

I recieved a great many helpful replies, many of which were folks who
checked to see what temperature their machines were and sent me that. Some
made this box seem too warm, others that indicated it was running at the
normal temperature.

Attached is an explaination for why that is.

Thanks to all,

Prtdiag is model-dependent.  Older machines, if they report temperature at
all, report "ambient" temperature, which is computer case temp and not all
that useful - for instance, our E-450s run about 37-42 C.  Newer machines
report "die" temperature, on the heat sink, or both.  Our Blade 100s run die
temps in the mid-60s and ambient in the high 30s.  If your 280R is reporting
only die temp, high 60s is probably normal, but you should hold out for a
comparison with other 280R owners.  My gut feeling is that if 69 is ambient,
your CPUs would be wafting through the air ducts by now, in vapor form.

Hello all. I have a Sun 280R that's been acting mysteriously (you can gzip
a file, but then gzip -d fails, etc) and I'm starting to
wonder if it's having a heat problem. "prtdiag -v" shows the cpu
temperatures thusly:

System Temperatures (Celsius):
cpu0   1
  64  62

That, to me, seems warm. This is a colocated box, and the cage seemed a
little warm the last time I was down there, which is what made me think to
check. Really, though, I can't put these numbers to use because the
information isn't in context -- I've no realy idea if that's way too warm,
or if it's within spec, and thought that one of your brainiacs might have
that information handy ;-)

And of course I'll summarize. Thanks.


PS: Solaris 8, if you were wondering.
