Also, the impressively large cooling surface and the replaceable fans really allow you to get the best cooling for your laptop while still letting you customize the fans to make the SF-19 your own. One thing I always look for when reviewing a laptop cooler is a USB hub. This is a great feature to have and the SF-19 is one of the few coolers I have reviewed that includes one. Not to mention that it's the first cooler that I have reviewed with a USB 3.0 hub.
