A laptop/notebook cooler, cooling pad, cooler pad or chill mat is an accessory for laptop computers that helps reduce their operating temperature which is normally used when the laptop is unable to sufficiently cool itself. Laptop coolers price are intended to protect both the laptop from overheating and the user from suffering heat related discomfort. A cooling pad may house active or passive cooling methods and rests beneath the laptop. Active coolers move air or liquid to direct heat away from the laptop quickly, while passive methods may rely on thermally conductive materials or increasing passive airflow.
Active coolers use small fans to generate additional airflow around the body of the laptop. This helps convect heat away from the device. The number of laptop cooler fans usually range from 1 to 6. Many cooler pads support the use of a power adapter, though they typically run on power drawn through one of the laptop's USB ports. Additionally, many cooler pads come with a built-in USB hub, so as not to consume one of the laptop's often limited number of USB ports.
Some active coolers draw heat from the underside of the computer; others work in the opposite way – by blowing cool air towards the machine. The fan speed is adjusted manually or automatically on certain models and on others stays at a fixed speed. Poorly designed coolers may use fans which draw more current than allowed by the USB standard. Without correct protection, such devices can cause damage to the USB power supply. Inside the laptop, the USB power-supply has to output an additional amount of watts for the USB-powered fan, thus generating a small amount of additional heat. This additional heat generation is usually insignificant in relation to the amount of heat a fan moves away from the laptop. Some high-end active coolers have blowers instead of fans, with filters to stop dust from entering the laptop, and have seals between the cooler and laptop surfaces to prevent recirculation of hot air from entering the laptop.
