When power is supplied to a PC component, the degree of heat generation may vary depending on the component, but all components except the case naturally generate heat. Among them, the parts that generate the most heat are the CPU, motherboard, and graphics card. Most PC cases are equipped with a cooling fan by default to exhaust this heat generated inside the case. In general, the way a PC case exhausts internal heat is as follows. First, it is a ventilation structure that takes in cool air from the front of the PC, cools the PC components, and then exhausts it out the back of the PC. Although there are some differences depending on the product, this is the basic cooling structure adopted by most PC cases. In the case of inexpensive products, many are sold with only one rear exhaust fan, and in this case, they are mainly used for low-spec systems that do not generate much heat. The recent trend in higher-end products is to place the power supply at the bottom and design an exhaust port that allows the cooler to be installed at the top of the product. In this case, most of them provide a front intake fan and a rear exhaust fan by default, and the top fan can be installed as an option. In this case, the consumer must purchase a separate cooling fan and install it on top. The most important thing to consider when installing is the intake and exhaust directions of the cooling fan. Some cooling fans on the market indicate the airflow with arrows, but many do not, so you must check this when installing an additional cooling fan. For most cooling fans, the direction in which the wind blows is the direction in which the guides that secure the center and outer housings are visible. In addition, if the CPU cooler you choose is water-cooled, the location of the radiator installation is important. Water-cooled cooler radiators usually range from one to four rows. Since they are rectangular plates, they are usually installed on the top or front of the PC case. However, if the case is too small to attach to the top section, all of the front intake cooling fans must be removed and the radiator must be installed in that section. Whether it is on the top or front, the intake and exhaust directions of the cooling fan that cools the radiator are very important. If the radiator is mounted on the top, the cooling fan must be installed in the direction of exhaust from the bottom to the top. If the radiator is mounted on the front, the fan must be installed in the direction of intake of air from the outside to the inside. #PCcase #Case #ABKO #Appco #PC #Danawa ▶Price information ABKO SUITMASTER 361G Callisto Tempered Glass DOUBLING http://prod.danawa.com/info/?pcode=56...
