I bought a new Dell laptop and but it has a serious problem!
Although I do not run heavy programs, its fan is in fast mode most of the time.
I tried out fancontrol, i8kutils etc but none of them worked.

I was wondering if somebody has had the same problem and a good solution for it

Check this:

Does this helps?

This page says it is certified to run on Ubuntu 16.04 LTS and image that comes from Dell https://certification.ubuntu.com/hardware/201707-25614/ It means if you removed factory Ubuntu, you removed some drivers too.

Another option is to run Dell diagnostic that is built into your laptop’s BIOS option https://www.youtube.com/watch?v=rMBIyeelQA0

Thanks a lot
I previously checked the link at Medium but it didnt work. As I got, it seems that dell has customized the pre-installed version of Ubuntu and as I have upgraded the installation, the drivers are all lost! But as you may know, its not so enjoyable to go to 16.04 because of a lot of lacking features.
I searched the web but I did not find the original dell version of Ubuntu

True. I understand. Try upgrading bios. See if it fix issue for you.

The following should turn off fan (both gpu and cpu for testing):

i8kctl fan 0 0

Set fan on low speed for both GPU/CPU:

i8kctl fan 1 1

What do you see when you run the following command?

For example I see following on my thinkpad x230:
