The second bomb was measured this week: how big is the memory cooling vest. Aluminum heat sink The memory heat dissipation is generally aluminum. Aluminum can conduct heat quickly, allowing heat to be evenly distributed throughout the heat sink, making it easier to dissipate heat. Compared with the original heat concentrated on the surface of the particles, the heat sink is theoretically more conducive to memory heat dissipation. But in the end, it still needs to be known through actual testing. This test platform The specific test method is: 1. Install the previous bare metal into the chassis and cover the side panels; 2, furmark donuts on the graphics card for roast chicken for 30 minutes; 3, at the same time memtest for memory stress test for 30 minutes; 4. Open the side panel and test with an infrared thermometer. Temperature without vest, 48.9 ° C. The temperature at which the leader's sword radiator is equipped, 44.3 ° C. After several tests, the average was taken, and no vest was about 4 °C higher than the temperature of the vest. Some people can't help but ask: In addition to a few degrees of difference, is there no other role? In fact, we all know that metal has the ability to shield electromagnetic waves, such as good quality SATA cable, with aluminum foil interlayer in the middle to ensure the stability of data transmission. Therefore, while the heat sink is dissipating heat, a layer of shielding is added to the memory to ensure stable operation of the memory. In the server field, due to the high stability requirements, the memory used generally has a vest. One is that the server memory uses the ECC error correction mechanism to cause a large amount of heat, and the shielding effect of the metal vest is also the overall. Stable operation provides a guarantee. Therefore, for users who are striving for stability, it is necessary to purchase memory with a vest. For example, the Q3 memory of the Terminator, which is the same price as the General Motors but is equipped with the vest, can be described as a "explosive".
