This device definitely works My Asus router seemed to overheat and freeze but now it doesn't. But it's expensive for what it is, and it's not even assembled for you. You need to screw the dust covers onto the fan and cut the stickers into the right size pieces to attach to the router. It comes unassembled as shown in the photos. There aren't many that I found to solve this problem in some Asus routers. But they could do better.
