The notebook cooler is with me a little misused because it cools no Notebbok but my almost brand new high-speed wireless LAN router from Asus, the RT-AC87U. The router is still quite warm, so I stopped in 24x7 operation it advisable to spendieren him a little cooling, and there works just fine. Since the router on the cooling pad is he is never more than hanwarm. Since you almost do not hear the fan of cooling pads in operation (I sit 1m away) I'm very pleased, especially since me the price seems reasonable.
