Hello! Sometimes I need my laptop Lenovo G50-30 is silent, need to switch off 
CPU fan.
Basically this laptop had no cpu fan but only passive cooling system. I had 
inserted cpu fan by my hands and there were fan power joint on the motherboard. 
This is nice. I hope Guix Linux-Libre has necessary fan control driver for my 
laptop.

There is package 'thinkfan' in Guix repository. Would you advice me how to 
config it and is it possible to switch off fan?

# thinkfan

ERROR: /etc/thinkfan.conf: No such file or directory
