Fashion appearance Same grille as supercar, simple and elegant Three core designs create efficient cooling effect 1.High-speed blower（2600-5000Rpm） Powerful engine, it is a high-speed blower with a maximum speed of 5000 rpm, while the fan of a traditional laptop cooler generally rotates at less than 1000 rpm 2.Tight silicon shroud（Available in three sizes） An air guide sleeve is installed at the connection with the laptop to prevent air leakage to increase the wind pressure and pull the hot air out of the laptop 3.Low-resistance air duct After the hot air is pulled out, it enters the air duct with low wind resistance to ensure the continuous and smooth circulation of the hot air How to judge whether your laptop or other equipment can be cooled by GT202UB? Whether the silicon shrouds match the heat dissipation holes of your device is the key factor. Your laptop should meet these requirements: 1. There is a side or back vent on your laptop and its size does not exceed about 4.6"L x 1.6"H 2. The bottom surface near the vent is flat to stick an adhesive mount 3. If the vent is on the back, please notice our cooler will cause the lid open about 135 degree
