CPU Cooler

To operate, the internal components of computer’s generate vast amounts of heat. To displace that heat, and make sure that the computer maintains a safe operating temperature, computers come equipped with a CPU cooler. It is important to keep a well-maintained CPU cooler, because, if a computer is allowed to overheat, high temperatures can cause equipment failure. The CPU, which is short for central processing unit, is the main housing for all the computer’s internal components – the motherboard, RAM, graphic and sound cards, etc. Depending on the size and age of the computer, the CPU cooler can be of various sizes or shapes.

CPU coolers come equipped on both desktop and laptop computers. For desktops, the CPU coolers are generally one or more fans equipped on board the CPU. In most brands of desktop, you will notice that the CPU cooler is designed to bring cool fresh air in at the bottom front of the case. This is why there is often a vent in that location. Further, they are designed to exhaust the warm or hot air from the top rear of the CPU case. If you are a desktop PC owner, you can feel around back of the case and often perceive the hot air escaping while the computer runs. Laptop computers, on the other hand, due to their small size, do not come equipped with onboard fans to use as CPU coolers. Recently, laptop design has improved enough that cooling is rarely an issue. Though, if laptops are allowed to overheat, they can experience significant problems, such as system failure.

People who “overclock” their computers often face special challenges when it comes to CPU cooling. Overclocking, in short, is the process of running a computer at a higher voltage or higher performance than manufacturer specifications. This process can generate more heat than the CPU was originally built to withstand, thus vastly increasing the chance for system or component failure. Many overclockers, though, have come up with solutions for this problem. For example, they may buy more expensive or top of the line fans and heat sink systems. A heat sink is a metal conductor designed to absorb and dissipate heat. Computer aficionados will install passive heat sinks near valuable components, allowing heat to disperse away from those components and reducing the chances of overheating. It is also possible to use an active heat sink as a CPU cooler. In this method of cooling, fans blow air over the heat sink. Sometimes it is preferable to use this method when generating a large amount of heat in the delicate CPU.

Data centers, where many varied types of computing equipment such as CPUs, servers, and other peripherals reside together, can present a special challenge when it comes to CPU cooling. Data center managers often take drastic measures to make sure that their equipment is kept cool. Failure to do so could result in the loss of the equipment, not to mention system failures on a business network, an internet site, an industrial process, or other information system that requires a large data center to manage. Data center managers can replicate the effect of a CPU cooler on a large scale by installing customized heating, ventilation, and air conditioning (HVAC) systems. For example, data centers may come equipped with a raised floor. The space beneath the raised floor can be used as a chamber to store cooling equipment or even cables.

Advanced techniques for CPU cooling include optimizing the air flow within the CPU, though there is little agreement in the industry on the effectiveness of different fan placement sites within a PC.
