"The NZXT Cryo S notebook cooler is a very well made laptop cooler that does its primary function well, while also providing several secondary benefits - such as the USB hub on the back, and the added benefit of having a keyboard that is tilted as to improve ergonomics. While the cooler didn't pack as large of a punch as its bigger brother, the Cryo LX, it is also quite a bit smaller, and perfectly fits my 15" MacBook Pro. This isn't really a cooler that you would take on a trip with you as it is rather large and bulky, but this is a problem that most people won't be affected by. As seen below, I have given the Cryo S our gold medal, which is one away from our highest award. This is due to the fact that on some laptops, especially Macs, the power provided by the USB ports cannot match the power drawn by the fans, meaning that the only option is to plug the cooler directly into the wall. Other than that one issue, this is an excellent cooler that will have a place on my desk for a while."
