First, the cooler is not as flat as in the picture, it is still a little "big", then, if your pc is a 17 "like mine, you will see beyond a few centimeters .
A disadvantage arises for those who do not have USB ports on the right side of their pc, bring an extension, otherwise you just pray that the cable reaches its destination. xD
Me finally, the blue LED is not too showy APART sides (Small openings for ventilation), and the fan guard, I recommend not to touch it, if you push too much, she has the air not too strong so I know too but I do not recommend. : - /
In short, I finally saw ° c down, and right overclock (On Laptops, yes yes), it is extremely convenient.
M'enfin the +:
Cools (Its main function xD)
Pretty enough
Cheap
the -:
Rather short USB cable
Grid "Not too" solid
I recommend it HIGHLY.
