Hello there!

Hardware noob here; I just updated my video card from a GeForce GT 440 to a Radeon HD 7950 (switching from Nvidia to AMD), however I'm noticing some weirdness.

Some sensor data (courtesy of GPU-Z):

GPU Core Clock: 300.0 MHz
GPU Memory Clock: 150.0 MHz
GPU Temperature: 0.0°C
Fan Speed (%): 30%
Fan Speed (RPM) 1105 RPM
GPU Load: 17%
Memory Usage (Dedicated): 192 MB
Memory Usage (Dynamic): 74 MB
12V: 12.06V
VDDC: 0.805V
MVDDC: 1.5V
VDDC Current 4.5 A
VDDC Current In: 0.3 A

After Windows loaded, my GPU fan transformed itself into a turbine, outputting at 100%.

Initially I thought that was MSI Afterburner or something trying to take control of the new videocard, but upon loading it up, I discovered that it was set to Auto control. I turned it on manual, and forced the fans to 30%. Whenever I let disable overclocking / fan control, it jumps back to 100%.

I'm not sure what caused this, however one thing I did notice is: AMD Catalyst and GPU-Z seem to think my GPU temperature is 0.0°C.

I was expecting better cooling, but that's just not believable.

What's happening?
Is this the cause of this the temperature not displaying?
Did I do something stupid? If so, what did I do (so that I never do it again)?

Thank you for any answers you can provide, wise computer gurus. I'm really hoping I don't have to return this :(

start with booting into safe mode and use a drive sweeper and remove all the video drivers. then reboot and install the newest driver from amd. if it still acts up check that you plugged in all the video card power plugs. your video card may be acting wired if your ps is under powered for the new video card.

Just an update: this did not work, and GPU-Z is still claiming 0.0 degrees celsius.

I'm going to try re-installing Windows, and re-installing the video card, but I'm starting to think this is likely damaged hardware... :( how come this always seems to happen?

can you feel the cooler of the gpu while running (carefully) to see if it is at least warm (should not be hot since it is idle)

0 deg is obviously wrong, do you have an updated gpu-z? old versions tend to report wrong numbers for cards that they don't know about.

if the heatsink is too cold maybe it's not firmly seated to the core, maybe you can visually check?

The GPU is warming up, and doesn't even go up while under load; I have every reason to believe that the 0.0°C is a lie.

I downloaded the latest copy of GPU-Z from Guru3D's site last night when troubleshooting this. Unfortunately, even AMD's Catalyst and MSI Afterburner isn't detecting a temperature...

I'll take a look at the video card again tonight. I'm fairly sure the issue (and the reason for the fan being at 100%) is a faulty / damaged temperature sensor.

I'll also check to make sure my power supply is providing a suitable amount of power for the new card. It should be enough though.

Did you manage to fix? I have exact same issue with new XFX R7970 DD...

I tried with 3 different catalyst/driver versions and with fresh win7 install, no luck... Most likely gpu sensor defect but wondering if it could be motherboard/gpu combination?

I too am having the same issue, brand new MSI R7950 Twin Frozr.

Haven't done a clean install of win7 yet, but I have used drive sweeper and a fresh install of the latest drivers with no result.

AMD, CPUID, GPU Temp and GPU-Z all fail to display a temperature for the card. However, when using AIDA64 Extreme Edition (trial) it shows a GPU temperature read for both VRM1 and 2 which idles around the 30°C mark (not sure if this is the same thing as a GPU read?).

My motherboard is an ASUS P8Z68-V PRO/GEN3.

Did either of you, or anyone else for that matter resolve your issue?

did anybody find a solution or cause for this? i am having the same issue with one of my sapphire hd 7970 ghz editions. i have tried drivers from the CCC days, and i have used the 2 most recent crimson drivers, and i just reinstalled windows. im thinking hardware failure as the temp went out about a week or 2 after i got the card. just wasnt there upon boot one day. really hoping my card isnt on its way out. i can deal with not knowing temps, i use msi afterburner to control my fan speeds on both my cards simultaneously. as my primary card gets warm and the fans speed up, my second card's fans speed up as well. i just want to know that my card isnt about to die

Try uninstalling all GPU drivers completely. I believe there's a software for that, something along the lines of DDU (Display Driver Uninstaller). Download that then use it to remove ALL drivers, current and past, then reinstall the latest GPU driver on the manufacturer's website.

I had the same issue with my Radeon HD 7700. While playing some game, the heat sensors suddenly stopped working, every program said my GPU was at 0°C and the automatic fan speed was constantly set to 100%.
Then yesterday I was playing Overwatch, but forgot to manually speed up my GPU fan, so after a while it just shut down and I got a black screen because of overheating. I restarted and SUDDENLY the heat sensors on the GPU worked again, same with the automatic fan speed.
So for some reason this just fixed itself for me by overheating.
The card doesn't seem to be damaged either.
