What are Laptop Coolers and How Do They Work?

Laptop coolers, or cooling pads, are external devices designed to provide additional cooling for laptops. These devices help to dissipate the heat generated by the laptop's components, particularly the CPU, improving performance and longevity. When a laptop's internal cooling system is insufficient, a laptop cooler can be a valuable solution.

How Dynamic Coolers Work

Dynamic coolers utilize small fans to generate extra wind current around the body of the laptop. This additional airflow helps to convect heat away from the device. There are various types of dynamic coolers, each with its own unique approach to cooling. Some coolers draw heat from the underside of the computer, while others blow cool air toward the machine.

Active Coolers

Active coolers use small fans to generate additional airflow around the body of the laptop. This helps to convect heat away from the device. Many cooling pads support the use of a power adapter, though they typically run on power drawn through one of the laptop's USB ports.

Dissipating Heat with Heatsinks

Dissipating sinks are designed to dissipate heat from certain parts, particularly the CPU. These components often consist of aluminum and either have a small fan attached or are part of the path for a fan on the side to move air across the heatsink itself. Newer laptops, especially smaller ones, often do not have built-in fans. If the CPU gets too hot, it can fail to perform well. Most computers will shut down before the CPU becomes too damaged. Heatsinks are similar to radiators in a car, and you've likely seen various versions on other devices, commonly made of aluminum with a bunch of fins.

Laptop Coolers vs. External Fans

Laptop coolers, which can also be called external fans, come in various forms. For example, a cooling pad with several fans attached can be connected to a USB port and blow air into the back of a laptop. These devices can be a life-saver for older laptops that use less powerful processors, as they are not designed to keep up with the demands of modern software. Dust accumulation can also be a factor, as laptops are designed to function without a cooling pad. If a laptop is not working as expected, it may be due to overclocking or dust clogging up the vents.

Using Laptop Coolers Wisely

While a cooling pad is a good idea if a laptop is overclocked, it may not be effective if the vents are blocked. Regular cleaning and maintenance of the laptop can help to prevent issues with heat buildup and improve overall performance. A cooling pad is a solution to address these issues, but it's important to ensure that the laptop is not running too hot and that the cooling pad is therefore effective.

Conclusion

Choosing the right laptop cooler depends on your specific needs and the issues your laptop is facing. Whether it's an older model with a slower processor or dust clogging up the internal fans, a cooling pad can help to improve the performance and lifespan of your laptop. Understanding how laptop coolers work and how to use them effectively can make a significant difference in your computing experience.
