Despite 5 fans that part is not noisy, like a tower computer with just few fans. It roars so softly ;-). And most important: The cooler keeps my Läppie fresh lot. the left palmrest next touchpad was always quite warm, now it is only lukewarm. And the Venties the laptop seem to run very little, because you can hear clearly normal. So who looks good notebook cooler for little money, makes nothing wrong here. Oh yes, and the provider is in complaints super fast and does everything the same.
