I needed a cooling system for laptop and I came across this one in which people can have fans as we please. I looked at the reviews and he seemed okay. Arrived Sunday ordered Tuesday morning packed properly. It is made of aluminum and some anti-slip rubber feet top and bottom. The fans are easily clipped anywhere you want in the grid. The carrier itself is nice, it extends 1 cm on each side on my pc 17 ". For fans they are very quiet, but I think they do not brew a lot of air. A dial on the side to adjust the intensity of ventilos. Despite the low fan power my pc really very hot when I'm on intensive games is pretty much cools. I am satisfied.
