What is a Laptop Cooling Pad
Nowadays, many people who own a laptop use it sitting on the floor, lying in bed or simply placing the device on their lap or right on a blanket. But the cooling system of a laptop is not able to withstand long hours of improper use. The air cannot flow freely around the laptop and thus the device overheats. In fact, the laptop gets hot even on a desk, causing damage to a device's performance. Eventually, this problem may lead to a system failure. So, to prolong a laptop service life and avoid overheating, use a laptop cooling pad. These pads are designed with special cooling fans that either suck hot air away from the system or blow cool air to it and thus protect the insides of a laptop from heat damage. Additionally, a cooling pad for laptop maintains the device temperature within reasonable limits. Now you don't have to turn a laptop off and wait till it cools down. With a cooling pad, you can freely place your laptop literally anywhere you want and work with it as long as you need.

What Features to Compare
Size and Material
Before purchasing a cooling pad, you should, first of all, make sure that it fits the size of a laptop you own. This parameter is measured in the maximal laptop diagonal a model supports. A cooling pad shouldn't be too small or too big as it will not be able to cool your laptop correctly and the machine will still run hot. So you should opt for a cooling pad that maximally conforms to a size of your laptop. Generally, cooling pads are made of plastic, metal, or combination of both. Plastic laptop cooling pads are quite inexpensive, lightweight and have poor thermal conductivity. These models cannot contend with metal ones for durability and they are not so sturdy. Additionally, the metal models boast higher capacity in heat conducting and thus cool down your laptop more effectively that the plastic cooling pads. To eliminate the problem of choosing between metal and plastic pads, the manufacturers offer models with metal mesh surface and plastic base. Such cooling pads are valued for their lightweight design, durability, and great results in heat conducting.
The most important features that impact a cooling pad's performance are the number of integrated fans and their power. Because these are the fans which effectively cool down a laptop. So, there are cooling pads with one big built-in fan in a center of a pad, while others feature several fans located throughout the pad's surface. It should be noted that smaller fans show more power in comparison with bigger fans. The reason for this is that the small fans require more power to spin a lot faster to generate the same amount of air the bigger fans provide. And it goes without saying that the size of a fan is not a crucial feature when choosing a cooling pad. The important parameter is the right location of fans inside a cooling pad. So, before you opt for a cooler, determine the hottest spots on your laptop and compare their location with the fans' arrangement. This way, you will achieve better results in keeping your laptop cool. But don't forget that the number of fans and power indexes affect the noise level of a cooling pad. Generally, most coolers show the noise level of about 24 dBA and work rather quietly. Laptop cooling pads operate from different power sources. The most widespread are USB-powered models. They require connection to your laptop to start operation. But there are also coolers powered by a headphone plug, by the mains, and even battery-operated pads.
Usability and Extras
It is preferable for a cooling pad for laptop to offer some extra features that are meant to provide a user with maximal usability. Hence, additional USB ports on a cooler are often demanded by people who connect lots of peripheral units to a laptop. Some cooling pads offer different fan speeds and adjustable height for you to fix the laptop at the appropriate viewing angle. So, if you prefer using a laptop on a desk you should definitely opt for a model with height adjustment. But for placing a laptop in bed it is preferable to look for a cooling pad with raised fans as the uneven and soft surfaces interfere with the air flow. Some cooling pads are designed with non-skid feet and/or ledges. The former provide the cooler pad with stability while the latter protect the laptop from falling off. Additionally, there are models designed with a special cable storage area in the bottom of a cooler to keep your USB cable away when you are not using it.
