Thanks everyone for the comments.
Well, as I was reading the comments on those page and some others, I noticed
that indeed my laptop was heating up more in the place where the disk is. So
I went to the BIOS and changed from ide to adci (or something like that). And
so far it has worked! No more kworker processes coming up, no more over
heating, the cpu is normal... I think it might have been a change in some
aspect of kernel update lately and it was necessary to change that.
For now I would mark this as solved :)
If anything goes wrong I will let you guys know :)
THANKS
