    GPU temperature

    ufimtsev

      What is the safe temperature for Radeon 6970? When I run one of our OpenCL programs, my GPU-Z reports

      GPU Temp: 97C, 

      GPU Temp #1: 97C, 

      GPU Temp #2: 110C, 

      GPU Temp #3: 102C,

      and the fan speed is around 60% (3700 RPM).

      Is it something normal or am I pushing too much?

      Thanks!

          Do you get the same readings from AMD Overdrive tab in Catalyst control panel? I would assume at 110C the GPU would have the fan at 100%, surely? These seem to be unrealistically high. If these temps are correct you are in trouble.

              Hi antzrhere,

              I have a bunch of GPUs sitting right next to each other and maybe this is a reason why they get that hot. I couldn't find the tab in my Catalyst so I downloaded AMD Overdrive instead. Bad news is that it crashed my win7 and I had to recover. Not sure why it happened, maybe because I use Nvidia cards for display... My primary question is how long it takes to fry a 6970 or a similar card under full load. I'll run the test and post here if find anything interesting.

                  Organize good ventilation, between the video cards insert matches to create the minimum gap, you can remove the rear plate(so you get an additional gap), screw substitute any (non-conductive) washers for clamping (to compensate for the removal of the plate) and if you do bitcoin, reduce the memory frequency up to 300 ~ 350MHz...

                  Organizuite horoshuyu ventilyatsiyu, mezhdu vidyeokartami vstavte spichki dlya sozdaniya minimalnogo zazora, mozhno snyat zadnie plastiny(tak vy poluchite dopolnitelnyi zazor), pod vinty podstavit lyubye (tokoneprovodyashchie) shaiby dlya obespecheniya prizhima(kompensirovat snyatie plastiny)  i yesli zanimaetes bitkoin, umenshite chastotu pamyati do 300~350MHz

                    follow as explained below to see temperature and fan speed in Catalyst.

                    start -> performance -> clock controls -> AMD Overdrive.

                    One more thing : Make sure your core clock and memory clock of GPU is set to default values if they are high.

                        On my system, there's no "start", no "performance", and no "clock controls" in Catalyst. I had to download the utility from the video card manufacturer to have access to fan controls. And even then the fan refuses to spin up to 100% under heavy load, unless the video card is used as the primary output (I have a multi-GPU setup).

                        Once I can actually get the fan to work at high speed, it's extremely noisy (so you can hear right away that it's working), but the temperature of the 6970 goes down to about 65 C, fully loaded with fan at 85%.

                        I don't know how long the GPU would last at 110 C, my guess would be "not very long", and it would probably crash all the time.

                    d.a.a.

                    I've a Radeon HD6970 on GNU/Linux. I'm using the latest fglrx driver (version 11.8), and its default fan speed is statically set at 25% and doesn't increase even when the GPU temperature reaches, for instance, 95°C--it is to reach that temperature running OpenCL applications. This is dangerous. I'm wondering why there isn't a dynamic fan control set up by default.
