A Variety Of Useful Cooling Systems Used In Personal, Laptops And Notebooks

Computer components which get heated up quickly are the CPU, Hard disk, graphics card and all integrated chips related Parts. These parts need a sufficient cooling mechanism within the computer. Cooling fans are the mostly used devices for air cooling of computer components like CPU, Chip sets, PSU, Hard disk and AGP card.

Cooling fan can be attached to the PC case, or attached to a CPU, chipset, PSU, hard disk or PCI slot. Notebook coolers are available in a variety of sizes, which include 40, 60, 80, 92, 120, and 140 mm. Some large size fans in the range of 200mm to 240mm have began hitting the market in past few years.

The quantum of airflow produced 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. Some fans come with an adjustable RPM rating to make less noise when the computer doesn’t need extra airflow.

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

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

In passive laptop cooling, a thermal conductive cooling pad permits for the cooling of a laptop without using any power. These “Pads” are loaded with an organic salt compound, that absorbs the heat from the laptop. Therefore the usage of cooling fans and cooling pads are very significant to maintain the temperature in the allowable range. When the heat crosses the allowable range, then it can lead to a CPU or a hard drive crash resulting in a complete breakdown. Most commonly used home or small business systems uses fan cooling systems.

Many systems where the sound of the fans is a great hindrance come with heat sinks and convection cooling systems, where the noise made is very negligible. Sometimes 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 researchers to find whether this technology could be used for cooling purposes.
