Only one fan of three detected #30

Closed Athlan88 closed 4 years ago

Hi!

The script only detects 1 of 3 GPU fans: onfiguration file: /home/aaron/nfancurve/config Number of Fans detected: 1 Number of GPUs detected: 1 GPU is Nvidia GTX 1080.

What is wrong?

nan0s7 commented 4 years ago

Are all three fans working reguardless? My script only uses the information given to it by the nvidia-smi command; so it will only detect the fan controllers (which can control multiple fans - my GPU, the 1070, has two fans and only one controller, so when I run my script it says the same as yours).

Athlan88 commented 4 years ago

Is there any way to tell except from opening the PC? Unfortunately I am not able to do this.

Hmm if you know the model of your GPU you can Google it. You can try looking through the nvidia-smi command/interface; check that any fans it detects are running at the proper speeds. If the temperatures are good and it shows that the fans are running properly, then there's no reason to believe what my script detected is wrong.

I get this response:

I can hear the fans spinning and the temperature is at 35°C, which is good. I think it works correctly, although I cannot tell if really all three fans spin or not.

nan0s7 commented 4 years ago

Well it seems to me that they're working. No reason to believe the fans aren't all being controlled by the script unless you can look inside the computer or the temperatures are incorrect. :)
