"The Vizo Mini Ninja is a small and portable way to cool your laptop, which is a haven for heat. While the benefits that the Vizo Mini Ninja provide aren't as varied as some other coolers, it does do its primary job well. In my testing, it actually helped reduce the CPU and GPU load temperatures further than any of the other laptop coolers I have tested. Not just 1 degree Celsius but by 3 on the CPU and 2 on the GPU. A pretty strong cooling performance."
