The chassis cooling can be seen from three aspects: 1. the internal space of the chassis;2. Cabinet air duct design;3. Chassis material.Personally, I think the cool chassis is generally good, but the price is slightly higher.The case quality is also very important. Simple judgment methods: 1. The internal structure design of the case;2. Thickness of steel (aluminum) plate used for chassis;3. Chassis weight;I personally recommend that if the price is below 200, don't choose Cool Cool. Basically, the cost performance ratio is low. If the price is between 200 and 300, I recommend using the Destroyer 2012 or the Saboteur, about 230 to 260 yuan. The interior space of the chassis is OK, and the air duct is also 4 air ducts.However, if your configuration is high and the heat dissipation is large, I suggest you use the Magic Armor about 450 yuan. This case is a tower type case, with enough internal space and sufficient materials.If it exceeds 500 yuan, it is not recommended to buy Cool Cool, but Yinxin Crow 3.Let me give you a little advice. In fact, no matter what configuration you use, I recommend you to use a mid tower chassis, such as the Magic Armor or the Crow 3. A good chassis plays a great role in the overall heat dissipation inside the chassis. If the air duct is reasonable, it can reduce the overall temperature by 5-8 degrees, and it will cost you more than 200 yuan to buy a good radiator.In addition, the chassis is a long-term accessory. Even if you upgrade the host in the future, you can continue to use the good chassis without replacing it.
