Hi lord_neno.
First, sorry for talking in English. I don't know too much Spanish and I think you'd not understand my brazilian portuguese.
I'd just like congratulate you for this post. I have a Z92T ASUS which I bought in Germany in 2006 and I had the very same problem you had. Following some of your instructions, I finally solved my notebook's overheating problem. And guess what: my notebook had the same f****** error about that alluminum piece over thermal "stone" paste. It took me some time to clean all that sh*t and see the same results as you.
I got a post reporting the same problem in a brazilian forum. Here's the link:

Again, thanks for this post and keep up the good work. You're helping a lot of people doing such thing. And sorry again for posting in English.
Regardings from Brazil.
