Four Development Stages of CPU Cooler

The first stage of its infancy

CPU cooler was born in 486 times, and at that time, the cooler was only a thin aluminum heatsink with the diameter of 4cm, and without a fan. Thin aluminum heat sink takes the use of the simplest aluminum extrusion process;

The second stages phase of the development

The CPU cooler has been widely used, while most of which are made of aluminum products, but there are a few copper coolers. And the cooler of this period has generally begun to use the fan, and thus brings the noise problem. Since then CPU heat is not large, so the very ordinary quiet cpu cooler will be able to meet the cooling needs. Fortunately, the generally cheap fan uses the very common industrial oil bearing, and the initial presentation of the use of oil bearing is in the good condition. However, with the growing of use time, dust absorption increased, and oil will evaporate due to the frictional heating, the fuel is gradually reduced, and the bearing friction and vibration are also increasing, resulting in increased bearing noise, increased wear and shortened the life expectancy;

The third growth stage

With the rising of CPU frequency and the scale of integrated transistor, the CPU temperature also grew exponentially and those cheap coolers in the past has far cannot meet the needs of the CPU cooling, while the demand for high efficient radiator is gradually put on the agenda. At this point, Japan, Europe and the United States, China's Taiwan Province, and South Korea and other countries and regions with precision machining and advanced electronics manufacturing processes, are beginning to adopt some new technology to manufacture radiators to meet the demand of the market. And this trend leads to two development booms: the first one is the bearing technology of the fan, and the other is the process technology of extruded heat sink.

The fourth stage of maturity

The appearance of P4E procured the maturity of the design and process tends of cooler, and the full copper heat cooler began to be spread by the virtue of the high heat transfer efficiency and moderate price, and becomes the mainstream product. Due to the large-scale production of full copper and heat pipe, the price is also quietly dropped and it is only slightly more expensive than pure copper, which is easily accepted by consumers. Pure copper and heat pipe radiator and water-cooled radiator also began to appear, its excellent cooling effect is impeccable, but the high price is also difficult to be accepted by the ordinary consumer.
