 |

hi
i have a problem with my :
| Code: |
kodi@myx51 ~ $ lspci | grep VGA
01:00.0 VGA compatible controller: NVIDIA Corporation GK104 [GeForce GTX 660 Ti] (rev a1)
kodi@myx51 ~ $
|
the fan is stuck att 34% in auto mode . when i set:
| Code: |
Option "Coolbits" "28"
|
in xorg i can adjust the fan manually and i have tried to find out what the problem is but
with no success.
regards
EDIT: at the momoent i have manage to get the card running with https://github.com/leinardi/gwe.git

- Have you checked using nvidia-smi?
- What happens if no driver is loaded (no nvidia, nor nouveau), besides efifb. Does it run at full speed then (as it should)? If not, then it might be a hardware related or VBIOS issue. |

thanks for the reply.it did not do anything.i switched to amd and did not bothered more with it as it was an old card and could not manage need for speed.

I've always had the problem, the default curves never go above about 40%, same in windows.
I've even had thermal throttling with the fans stuck under 40% in auto mode.
There is a fan curve editor in windows which will (mostly) fix the problem, for Gentoo I had to write a script to deal with it.
If you are interested in the script let me know, it's been running for about 18 months without problems. |

ATM i am running radeon-profile . but it is not the best way because i need to have a lot of stamps for the fan to work good.
how do your script work? . |

Small daemon written in python monitors the temp in /sys/class/hwmon, when the temp goes over a preset value it switches to "manual fan control" and applies a pre-defined "temperature to fan speed" curve.
I've altered the script to serve 3 different applications, it runs the GPU fans on my desktop PC, another version runs the fan on my Pi, and the 3rd version throttles my laptop CPU to keep the temps down, most of them been running well over a year with no problems now.
I'll dump the code here, shout if you need help altering it to fit your system.

Needs to be run as root to poke values in to the relevant files in /sys, needs python 3.x to run, and obviously hwmon support. |

Hay Ralphred, thanks for this python script.
