CPU is the most difficult hardware in industrial computer. Why do some people burn out their CPU when using an industrial computer?
The CPU of an industrial computer is the same as a commercial ordinary computer. We use Intel's CPU and the warranty is 3 years. If it is used normally, it is rare for ordinary computers to hear that the CPU is damaged in 3-5 years. We have heard relatively a lot about hard disk, memory, motherboard, power supply, and display failures. For some customers who use industrial PCs, they say that the CPU is burned out. What caused it? Let's explain to you in detail the situations in which the CPU of an industrial computer is burned.
1. Voltage problem.
The voltage of the industrial computer is within a stable range. For example, in our industrial computer IPC-606, the 12V input from the computer after passing through the power adapter is input into the industrial computer. The electronic components inside the industrial computer have standard power. If some customers do not use the power adapter that we configure, use 19V or 24V. Because the voltage is too high and the current is too high, the power is too high, and the electronic components on the motherboard are instantly burned out.
The CPU of the industrial computer is on the motherboard. If the motherboard has a problem, the CPU may be burned.
2. Heat dissipation problem.
Many industrial computers use fanless cooling systems, relying on heat dissipation blocks and casings to transfer heat to the body. If the internal temperature of the industrial computer is too high to be exported in time, it will cause the temperature of the CPU to be too high, causing the CPU to slow down or even be burned.
Generally speaking, the heat dissipation of industrial computers produced by large companies has passed the heat dissipation test. If the industrial computer is used for a long time, the internal thermal paste and heat sink will expire, causing the heat of the CPU core to not be transmitted to the outside in time, and the cover needs to be opened to replace the silicone grease.
3. the motherboard problem.
When choosing the CPU of an industrial computer, consider whether the CPU is compatible with the hardware of the industrial motherboard. Some industrial motherboards produced in small factories do not work well with the CPU, resulting in unstable power supply, and it is extremely easy to burn the CPU.
4. second-hand CPU.
Some customers are like cheaper, and some small factories use second-hand CPU processors. Due to the use of these CPU products, some gold fingers have been seriously oxidized. In addition, the previous usage is unknown, this CPU is easily damaged by overclocking.
5. Installation problems.
The CPU must be installed with good pins. Some factories are not very professional in assembling industrial computers, and they are reversed during installation and the pins are damaged. Change it back to use later. Due to a small problem with the pins of the CPU, the voltage is unstable or there is no way to damage the normal power supply during use.
