Why the cooling film will cause the CPU to fail

Answer: First of all, using the replacement method to eliminate the graphics card, memory and other hardware problems, the focus of the CPU check. After careful review, I found a lot of rust on the copper pins on the CPU chip. After careful cleaning with a toothbrush, install the computer, the boot detection normal. According to the phenomenon inferred, is because the refrigeration effect of semiconductor refrigeration is too strong, cause the chip surface temperature drop too low, even below knot dew point. CPU long-term work in the humid environment, oxidation of copper pins appear on the patina, which caused the CPU chip and motherboard socket contact bad fault. Users who use the refrigeration slice should check the CPU monthly to prevent such failure. In addition, it is recommended to purchase a refrigeration film with an automatic thermostat circuit.
