Since qq months my laptop was becoming constantly burning, I could hear the ventilation force especially in game phase I ended up lest he let go for good. A cleaning ventilation with air under pressure was not sufficient. So I decided to turn to one last hope, and I do not regret it at all! - Very light (it gives the impression of being suddenly toc though) - Very quiet, we hear just a slight breath - My computer is cool now see a little warm in game phase, I never hear ventilated row.
