This are notes for configuration thinkfan for Fedora. This configuration procedure was followed on a Lenovo Thinkpad X1 Carbon (5th Gen) running Fedora 25.
Non standard (default) configuration was required for this machine as the default sensors are not available. Eg: /proc/acpi/ibm/thermal does not exist for this model.
An annoted configuration file has been included below. However, there is no guarentee that this will work as-is on every machine.

| Create a virtualenvs directory to store all virtual environments | |
| $ mkdir somewhere/virtualenvs | |
| Make a new virtual environment with no packages |
