a python script with a GUI that creates a modifiable 2D curve of [temp, speed] points that are used to control the fan speed of a Nvidia GPU within a Linux environment.

• Install python:
  sudo apt-get install python
• Install matplotlib:
  sudo apt-get install python-matplotlib
• Install Tkinter:
  sudo apt-get install python-tk
• Install pyGTK:
  sudo apt-get install python-gtk2-dev
• Install libcanberra-gtk:
  sudo apt-get install libcanberra-gtk-module
• Allow the Nvidia card's fan to be controlled:
  sudo nvidia-xconfig --enable-all-gpus and sudo nvidia-xconfig --cool-bits=28
• Reboot your computer for the GPU settings to take effect:
  sudo reboot
• Open a terminal in the folder containing nvfc.py, then execute:
  python nvfc.py

• Apply - Applies the curve to the GPU fan for the duration of the session
• Reset - Sets the curve to default values (can be values from config.csv)
• Save - Saves a config.csv within the app directory (if missing, loads a default curve)

• Temperature - Current GPU temperature (°C)
• Fan Speed - Current GPU fan speed (%)

⚠️ Only works with nvidia proprietary drivers

⚠️ Versions 349.12 and 349.16 are not supported due to a regression in the drivers

⚠️ No SLI support (only single GPU configuration)

⚠️ It currently must be used with an open terminal

⚠️ Closing the app resets the GPU fan speed to auto (controlled by driver)
