Different Efficient Cooling Systems In Personal, Laptops And Notebooks Computers

Computer parts which get heated up fast are the CPU, Hard drive, graphics card and all integrated chips related Parts. These parts require an enough cooling mechanism within the computer. Cooling fans are the mostly used devices for air cooling of computer parts such as CPU, Chip sets, PSU, Hard disk and graphics card.

Cooling fan could be attached to the computer case, or connected to a CPU, chipset, PSU, hard drive or PCI slot. Notebook coolers are available in many sizes, which include 40, 60, 80, 92, 120, & 140 mm. Some big size fans in the range of 200mm to 240mm have started hitting the market in recent years.

The quantum of air flow generated by fans measured in cubic feet per min (CFM), and speed of rotation of the fan is measured in revolutions per minute (RPM). Fans with greater CFM rating, but produce less noise (measured in decibels) are preferred. Many fans come with an adjustable RPM rating to produce less noise when the computer doesn't require extra air flow.

The speed of the cooling Fan can be regulated manually, thermally, or by the computer hardware or by software. In case of laptops and notebooks, if the cooling fans are not sufficient to cool the components, then a laptop or notebook cooler is used for cooling . In this cooling is done by a cooling pad by passive or active cooling methods and rests below the laptop.

Active laptop cooling fans pass air or liquid to take the heat away from the laptop quickly, while a passive lap cooler uses thermally conductive elements for cooling purposes. Laptop cooling fan speed can be adjusted manually or automatically on different models. On many models, the fan runs at a fixed speed.

In passive laptop cooling, a conductive cooling pad allows for the cooling of a laptop without using any power. Those "Pads" are filled with an organic salt compound, which absorbs the heat from the laptop. Therefore the usage of cooling fans and cooling pads are extremely significant to maintain the temperature in the allowable range. Once the heat crosses the allowable range, then it can result in a CPU or a hard drive crash resulting in a total breakdown. Most commonly used home or small business systems uses fan cooling systems.

Some systems where the sound of the fans is a great hindrance come with heat sinks and convection cooling systems, where the noise produced is very negligible. Often the motherboards would be completely immersed in liquid oil, that is an alternative to both cooling fans and heat sinks. Ionic wind cooling, which doesn't use any cooling fans or sinks are currently being researched by the research workers to find whether this technology can be used for cooling purposes.
