This system saved me a new PC, in fact I could not make anything complex (video editing, file conversion, management photos ...) without my laptop does séteigne every time. The principle of adjustable fan is an idea of super efficient engineering. However the platform is a worthy ugliness equipment of the USSR era but with that wire and USB tip which are very cheap. Anyway it's ugly but very effective and it is essential in my case. I tested the other system before this one but it is the only one that has dramatically cooled my PC to the point of not having Darret of the machine even on super heavy tasks. So I recommend this system to anyone who like me have a laptop that goes off at the slightest overheating and do not want to invest in a new laptop.
