Một số máy tính trở nên ấm khi sử dụng lâu, trong khi số khác có thể hơi nóng. Điều này bình thường: đây là cách máy tính làm nguội chính nó. Tuy nhiên, nếu máy tính bạn trở nên rất ấm, có thể đó là dấu hiệu toả nhiệt quá nhiều, và có thể dẫn đến hư hỏng.
Most laptops get reasonably warm once you have been using them for a while. It is generally nothing to worry about — computers produce a lot of heat and laptops are very compact, so they need to remove their heat rapidly and their outer casing warms up as a result. Some laptops do get too hot, however, and may be uncomfortable to use. This is normally the result of a poorly-designed cooling system. You can sometimes get additional cooling accessories which fit to the bottom of the laptop and provide more efficient cooling.
If you have a desktop computer which feels hot to the touch, it may have insufficient cooling. If this concerns you, you can buy extra cooling fans or check that the cooling fans and vents are free from dust and other blockages. You might want to consider putting the computer in a better-ventilated area too — if kept in confined spaces (for example, in a cupboard), the cooling system in the computer may not be able to remove heat and circulate cool air fast enough.
Some people are concerned about the health risks of using hot laptops. There are suggestions that prolonged use of a hot laptop on your lap might possibly reduce fertility, and there are reports of minor burns being suffered too (in extreme cases). If you are concerned about these potential problems, you may wish to consult a medical practitioner for advice. Of course, you can simply choose not to rest the laptop on your lap.
Hầu hết máy tính mới sẽ tự tắt nếu trở nên quá nóng để giảm thiểu hư hại. Nếu máy bạn cứ tắt hoài, đây có thể là nguyên do. Nếu máy bạn quá nóng, bạn sẽ cần đem sửa.
