fancontrol – Dell Vostro 200 fan speeds

I recently installed Ubuntu (18.04.1 LTS) on my previous desktop to use it as a server. I've been trying to manage fan speeds, but I can not make it work.
I started with this tutorial:
How to control the speed of the fan?

After that did not work, I read that Dell needs a little more work and I tried this:
Fan speed in Ubuntu: pwmconfig no sensor modules compatible with pwm installed

But pwmconfig still says No sensor modules compatible with pwm installed.

And i8kctl only gives me this: 1.0 1.0 BJ17YG1 -1 -1 -1 -1 -1 -1 -1

I'm not even sure if i8k is for Dell desktops, maybe just for laptops.
If someone can help me, it would be great, Thanks!
