Now there are different sizes of small pads which are made particularly for cooling devices that may overheat. The devices include laptops, mobile phones, tablets, modems, and routers. The cooling pad is a horizontal fan that is inside a slim chassis. The height of the fan is not too high so that the user can be in discomfort while using the device. The fan receives the power through a USB power port.

So, when you place your modem on the cooling fan it will blow constant cool air and will not allow your modem to overheat. Therefore the problem is prevented. If your router doesn’t have a USB port you can use a USB power port that is close by.

Do not place random things on and around your modem

Many times overheating problem occurs because the modem is not getting any proper air circulation. This problem can happen when you place unnecessary things around your modem. For example, if you place your modem against your wall. The wall may be the reason that is preventing the circulation of air into the modem. Or if you may have an animal that likes to sit beside your hot modem that can also cause air circulation issues. You can place your modem on a raised flat surface and provide some space behind and also on the sides for proper circulation.
