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. GTS wrote: wrote in message ... I recently bit the bullet and built a new machine: double Xeon configuration with a GeForce FX5900 by Gainward.

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. |

This seems like a much more reasonable value. IMHO they start throttling after 100°C from the onDie diode ... -- Regards, SPAJKY ® & visit my site @ http://www.spajky.vze.com "Tualatin OC-ed / BX-Slot1 / inaudible setup!"

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. What would be a reasonable operating temperature for the GPU and at what temp should I flag a temperature alert? 70° would be Ok IMHO I agree. I think 70C should be top end for safe semiconductor operation. The Xeon CPUS automatically throttle back at 71 celcius. This seems like a much more reasonable value. 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. What would be a reasonable operating temperature for the GPU and at what temp should I flag a temperature alert? 70° would be Ok IMHO I agree. I think 70C should be top end for safe semiconductor operation. 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. The Xeon CPUS automatically throttle back at 71 celcius. This seems like a much more reasonable value.
