CPU cooling technologies

Updated on July 23, 2011

Keeping your cool is important, but keeping your CPU cool is even more important. The CPU of your PC has to stay cool so it can continue with its normal operations. The CPU is one of the PC’s biggest heat-producing parts, and this is where most of the noise comes from in your PC, its the noise of the fan keeping the CPU cool. You will find most motherboards today, have an on-board CPU heat sensor and CPU fan sensor. This is especially true for laptops, since they can easily reach dangerous temperatures due to the small space of the components. The most common method used to dissipate the heat generated by the CPU is to install a heat sink right on the CPU. You can also use a special chemical called a thermal compound which is placed between the CPU and the heat sink to improve the heat transmission between the CPU’s surface and the heat sink. The heat skin is one of the biggest things inside your PC. Its a huge chunk of metal that just spreads the heat away from the CPU. The noisy fan is located on top of the heat sink that blows the hot air away from the surface of the CPU.

Phase cooling

If you are a PC enthusiast looking to squeeze as much as possible from your pc's performance, then no doubt you will be overclocking the CPU of the PC. This is just like increasing the speed of a car engine, to make it go faster. The problem is that the CPU over heats more than normal and can cause damage. This is why heat sinks have been developed with heat pipes to take away the heat from the CPU surface. Some PC manufacturers actually use CPU coolers that are made up from heat sinks made of copper plates and high-performance cooling fans. You can also buy a liquid cooling system which again uses water or a special type of liquid to dissipate the heat. is used to keep the CPU cool.

The best advantage of a liquid cooling is that the cooling parts don't make any noise like the fan systems. Another new type of cooling system is Phase change cooling. This is a more extreme cooling technology that uses the phase change from liquid to gas. The phase change cooler unit basically contains a small compressor , like the one that is used in fridges, and freezers . The compressor unit is located under the computer. The compressor squeezes a cool gas in and then condenses it to liquid form. The liquid is then pumped through to the CPU through a pipe, which heats it, this then causes its own heat to dissipate.

      Great information here. I am having a heat problem - I thought the brutal heatwave here in New York City with high humidity was making my fan work harder. Add that to the reduced voltage of the power company. I thought it best to just shut down.

      Back to normal summer weather and the keyboard feels much better.

      When I buy a new laptop I am going to look into the liquid cooling.

      Thanks for the information! Rated up!
