Dell Fan Cron Job

This script written for Dell Inspiron Laptops. In my laptop CPU Fan is allways running at top speed. So I write a script to control cpu heat and manage fan speed with a cron job.

###Requirements

1. You must have loaded the i8k module

Ubuntu: sudo modprobe -v i8k

2. You must also install i8kctl

Ubuntu: sudo apt-get install i8kctl

3. After Installing i8kctl you must run this line:

sudo sed -i.bak 's/ENABLED=0/ENABLED=1/' /etc/default/{i8kmon,i8kbuttons}

4. You must have sensors

Ubuntu: sudo apt-get install sensors

You have to check sensors command to see it shows cpu heat.

###Installation

If you want to run your cron job for all users you must open crontab with root user.

sudo crontab -e

Then add this line;

*/1 * * * * sh /path/to/script/del-fan-cron.sh

Note: I'm using Dell Inspiron 5110 and it has only right fan. So i didn't manage second fan. If your laptop has second fan, you must edit this script.
