Default reasonable GPU alert temperature

I recently bit the bullet and built a new machine: double Xeon configuration
with a GeForce FX5900 by Gainward. The CPUs run in the lower 40s celcius,
which is excellent, but the GPU on the graphics card runs a bit hotter.

After the system has been up for a while X-windows or win-XP, the GPU
core temp registers in the upper 50s. the driver software shows a default
core slowdown temp of 140 celcius and this seems WAY HIGH!

What would be a reasonable operating temperature for the GPU and at what
temp should I flag a temperature alert?

The Xeon CPUS automatically throttle back at 71 celcius. This seems like
a much more reasonable value.

Did some doofus who wrote the driver software put a farenheit value in
as a default that should be listed in celcius?

Any thoughts?

I have a 5900 'vanilla' and idle temps are GPU 46-47c, ambient 35-36c
After gaming with i.e. Farcry the GPU reaches 65c or so.
You did'nt mention the ambient temp as stated in the Nvidia control panel -
so could it be poor case cooling? If you are using a 5900 XT or SE I think
they use smaller cooling solutions (my 5900 is a double-height card, using
up the space of the PCI slot below the AGP)

I have a Gainward FX 5900 Ultra, not overclocked. Its running 46
ambient 55 GPU right now. Immediately after Doom3, it would hit 60 amb.
70 GPU when running on highest settings, more like 50 amb. 60 GPU when I
ran it on the next highest setting. System has been very stable.

Look for a program called rthdribl (use google), its a DX9 stress test that
runs in window.

Leave the Nvidia temperature tab open while the above program runs and watch
the temperature climb. After about 20-30 minutes you'll know your max GPU
temperature.

Or better still get yourself the lil app called RivaTuner and have it
running in the background recording the card temps. I have seen as much as
an instant 20 deg C core temp drop from the moment of exiting 3D back into
2D so checking temps when dropping back in desktop via the nVidia control
panel is not the best way to read the temps.

Buy the way during this very hot time we have been having here recently I
average 79 Core / 45 Ambient in games, Gainward FX5900 Ultra flashed to
FX5950 running 516MHz Core / 1.02 GHz RAM.

sensor is bad! or
a farenheit value maybe?


This is the value that was entered as a default as to when the GPU should
fall back to a slower speed. Yes, my guess is that the programmer put
a farenheit value in where they should have used a celcius value...This is
what I'm trying to determine.

70° would be Ok IMHO


I agree. I think 70C should be top end for safe semiconductor operation.

IMHO they start throttling after 100°C from the onDie diode ...


I think you are mistaken. According to the Intel product documentation the
maximum operating temperature for the Xeon is listed as 71C.

Overall, the system doesn't seem to overheat. Ambient temperature in the
case is in the mid 40sC. The CPUS are in that range, and the NVidia GPU
usually runs in the mid 50sC. I am not doing any real 3D stuff (YET):
just Linux X-windows and win-xp, with an occasional simple OpenGL wireframe
of a cave map or some other engineering drawing.

The power supply fan output is pretty hot, but the internal case temp seems
well within acceptible limits.

Thanks

My PNY 6800 GT is set at 120C. but unless the fan dies it's not going
anywhere near that.

Too bad because any 3d operation is going to spike up the temp at least 20
deg. Mine tops out at about 82C from an idle of 61C or so. Ambient shows
46C. I do have a 50Mhz OC on the core.

since the introduction of IHS on their CPUs, IMHO Intel gives specs
for max. long term full load !!! reliable operation temperature
measured by the temperature of IHS. That means that onDie diode
one is at least 10°c higher @ idle & 15° higher full load. That means
that if CPU fan dies , you have 70° on the bottom of the HSF (IHS),
but inside the core /cpu diode/ you have there @ idle 100°C (which BTW
is also declared handling/storage max value) & IMHO thermal throttling
should not kick_in much before that to slow down the sistem.
Thermal throttling will keep Cpu die below 120°C (remember
that famous video with running it w/o a HSF & not crashing OS!) if HS
looses contact (or badly mounted) with IHS ... Second thermal
protection incorporated onDie, will shut down CPU at IMHO if reaching
125°C /quite general rule; in industrial inviroment that temps are
generally higher/.
On some MoBo´s, you can set also inside Bios thermal
throttling at dedicated temp (also warning & shut down ones too).
That for precaution or a thermal runaway I´ve done for my Tuallie when
I was for testing running it w/o a fan OC-ed in closed case with a bit
bigger HS than original. (max I was running it max throttled by mine
MoBo @ almost 90°C from onDie measurement w/o crashing my OS - but was
slow as a dog!) & IHS temp barely rised over 60°C !
Check my site under comp/benches to see some mine temps with
different fan speeds & imagine P4 /or Xeon/ temps than while it
consumes more than double power than my Tuallie ... (my temps are
correct ones - sensors properly calibrated!)

about GPU:

IMHO its HS temerature should not exceed 80°C (means that
inside GPU would be around 100°C even if Fan cooled HS ...
mine prehistoric video card /passivelly cooled with added bigger HS/
craps out after 70°C HS temp (inside GPU there could be same around
100°C)

That my CPU fan experiment there I mentioned before with
lowering fan RPMs & consequencies can be applied also on graphics card
cooler when lowering voltage of a GPU HSFcooler avoiding loud
"turbine" sound coming out from the PC case ... :-)

the real problem is to exactly know, how the temps on CPUs & GPUs are
measured by the certain MoBo/graphic card - where & what kind of
sensor is used while the monitoring program is showing temps
even properly calibrated & set ... (or some latest drivers have
interface for GPU tweaking & monitoring temps of GPU, but has to be
verified what kind of sensor is used anyway on a graphic card & where
is situated ...)

About setting the alarm temperature for GPU :
I would set it a degree or two less than running for awhile Doom demo
in loop on the hottest summer day ... before it freezes the PC! ...

sorry for the long post; but I think it could be informative & useful!
