"And we're back again with another notebook cooler review, or in this case, a pair of notebook coolers for you guys to check out. They come from VIZO, a well reviewed company here at VH, and are geared for low noise and adjustability. The full sized unit goes by the name of the Ninja HS, with the smaller unit going by the Mini Ninja. Overall the Ninja HS is a pretty nice notebook cooler for those in need of something totally silent. I wouldn't use this to cooler high power (and high heat) gaming laptops, for the majority of you out there, this should be just fine and certainly better than using nothing at all."
