38 degrees chassis, a chassis term. Was a 38 ℃ temperature index on the chassis,
air force one low nike, Tracing the source, then the index is from 38 ℃ to start talking about how too. In accordance with the intel to say, when the buckle cover of the chassis, CPU heat sink temperature at the top of 2CM represents the internal temperature of the chassis, the chassis is the number of degrees, at present, generally have their own PC DIY's around 42 degrees, so 42 degrees is called the chassis, not difficult to understand from here, the chassis refers to the so-called 38 ℃ CPU heat sink can be 2cm above the temperature controlled at 38 ℃ in the chassis.

Introduction Introduction to the origin of the principle structural advantages of seeing for example the summer is coming, the temperature within the chassis is rising. To the current CPU, both the AMD Athlon XP or P4 INTEL's a million transistors, with the increasing CPU power consumption, are facing a serious challenge, that is, CPU's heat. How to make your love Chassis is a chassis 38 degrees terminology, most of the experts to the chassis to divide the enclosure internal temperature. After the chassis cover when fastened,
nike air force 1, with the processor to indicate the temperature above the heat capacity, heat sink temperature, the number of degrees above the call number of degrees chassis. The chassis on the market from the current market view, DIY market basically internal chassis temperature of 42 degrees. Experts call it 42 degrees chassis. However, with the rapid increase in CPU clock speeds. Users while enjoying the pleasure brought by high-speed operation, but also increasingly for the high-frequency processors, heat dissipation and headache. From the perspective of manufacturers, although the current maturity of the 0.13-micron manufacturing process of the cooling solution is perfect, but the face of the future high-power AMD Athlon 64 bit processor and INTEL's Prescott Pentium4 will no doubt be a bit powerless. So the major manufacturers will be in the original chassis structure has been modified to ensure the CPU temperature over 38 degrees. This case is also known as 38 degrees chassis. The origin of the heat as more and more processors, Intel processors in order to ensure a safe work environment, so they launched a chassis cooling standard test CAG (Chasis Air Guide chassis cooling airflow design specifications) specification,
air force one high, this specifications designed to test various components within the chassis cooling thermal solution, Intel introduced the CAG1.0 2002 standard, that at 25 ℃ room temperature, the provisions of CPU heat sink chassis 2 cm above the average temperature of the four points can not exceed 42 ℃ With the rapid increase CPU frequency,
nike air force 1 high, heat is also soaring, to calmly deal with this situation,
nike air force one, Inte launched in 2003, almost at the harsh CAG1.1 standard, that at 25 ℃ room temperature, chassis, CPU cooling 2CM devices at the four points above the average temperature should not exceed 38 ℃, to achieve this standard chassis, the chassis is referred to as 38 ℃, which is the origin of the chassis 38 ℃. 38 degrees refers to the so-called case is in line with INTEL's TAC1.1 certified chassis. To know what is TAC1.1, first of all have to say about CAG specification (CHASSIS AIR GUIDE, cooling duct design) This is the concept put forward a long time ago, there is no cause for concern because the former is not CPU-heat reasons too. Its purpose is to enable the external cold air directly into the chassis to the inside to get a better cooling effect, it is proposed to improve the structure of the chassis, and contains the CAG TAC is a more comprehensive certification. CAG TAC can think of an upgrade, which includes the area and want to send in more detail. To purchase to meet the CAG1.1 case a rectangular chassis side vents open, and covered with metal mesh shielding of radiation in the air vents on the PCI card is needed to heat the cold air. Only meet the above four conditions can be called The focus of this design is to reduce the processor temperature, while allowing some of the core (processor, chipset) motherboard layout according to different regional design movement. The overall goal is to provide a minimum at minimum cost and impact of integration applied to different motherboard, and can be easily integrated into current and future chassis design of the cooling program. Xin Gu chassis instance: that the use of chassis air guide duct when the expected type of an example. The platform has a typical 80 mm rear fan and a power supply system on the 80 mm fan. Both are from the chassis and exhaust fans (blowing air), cooling system components provide the required airflow. This configuration caused the fan inside the case outside the box just below atmospheric pressure. Thus, all other openings on the chassis have become the air inlet. Now, the main air inlet is open and the chassis front bezel Air Guide. Processor fan and heat sink combination can be directly inhaled the air outside the box is still an important part of the processor cooling. Flow balance for the other system components to ensure adequate cooling is still extremely important. This case involves the front and side of the chassis to provide adequate open area so that all parts are received to the desired gas flow. Without proper air flow balance, some parts may be below the required temperature in the run, while others may be at higher ambient temperature operation. Air balance is not easy to grasp, but if control is correct, all the system components can be in the recommended temperature range operation. The chassis is constructed of 38 degrees in the original chassis structure designed. With the previous case is no different from the shape point of view, but its structure than to have two different lives. First point: The new re-designed the CPU heat sink. The commonly used aluminum CPU heat sink normal production, processing, good surface treatment is easy, low cost; by the fan on the heatsink fan to the following heat transfer through the top, forming a one-way air flow, for at this stage processor or with a strong heat dissipation. However, with the emergence of next-generation CPU core, so that the heat sink structure will not meet the need. So the CPU heat sink structure in the selection and made a revolutionary change in the use of copper alloy on the selection of a combination of programs. Thermal conductivity of copper is almost twice as much aluminum, the heat can be transferred to the uniform external heat sink. Mixture of copper and aluminum cooling effect of the guaranteed price when the cost of control. At the same time the structure of the heat sink, a change to live a normal two-way heat, using the four directions from the inside out at the same time heat transfer work, so the heat sink thermal performance is twice the increase. The second point: the change from the chassis structure. CPU heat sink in the left side of baffle on the top of the chassis out of a cooling vents, CPU heat sink and cooling vents with a ventilation pipe connected between the effective guarantee of the internal chassis air temperature and the external balance. CPU cooling advantage of a variety of ways, but considering the cost and use, to the best air-cooling. And increase the cooling effect of the most direct way is to increase the fan speed. But this result is that although the high temperature heat to disperse, but to bring loud noise. In order to take into account the cooling and quiet, some friends hope water cooler. To the domestic market as things stand now, the price can make the average user to accept, good cooling effect, and in noise control, ease of use and security on and have a considerable assurance, that water-cooled product did not exist. The players can do so in full compliance with the requirements of water-cooled equipment, the price is easily up to thousand dollars. Therefore, a high-quality air-cooled heat sink is still the best to meet user requirements. The emergence of just 38 degrees chassis solution to this difficult decision. Copper and aluminum heat sink heat sink to the bottom of the rapid absorption of the CPU's temperature, even four passes to the heat sink. The cold air outside the chassis to achieve through the ventilation pipes directly above the CPU, cooling fan speed remains under the original fan,
air force 1 high, the fan quickly blowing cold air over the copper and aluminum heat sink, so that rapid cooling heat sink to ensure the chassis temperature of 38 degrees. You need not to machine the face of summer temperature is too high due to machines swing machine asking this question. Cooling effect of the decision level of technology, it is eternal truth radiator products. Intel and AMD continue to increase frequency, high power consumption will inevitably bring more heat, in this context, how to solve the cooling performance of the machine, will be the future trend of computers. Xin Gu chassis instance example: that the use of chassis air guide duct when the expected type of an example. The platform has a typical 80 mm rear fan and a power supply system on the 80 mm fan.
