熟悉笔记本电脑的消费者可能会注意到这样一个现象,那就是笔记本电脑的 CPU 主频往往比同一时期台式机的主频要慢一些。比如,目前最好的 CPU 芯片的主频已经在 1GHz 以上,而目前主流笔记本电脑的主频大多在600MHz 至850MHz 之间。这其中的原因就在于笔记本电脑的散热问题。散热问题对笔记本电脑来说是一个非常关键的性能指标,散热问题解决不好,笔记本就无法使用。我们知道,随着CPU 主频的不断提高,以及其它可控处理芯片功能的日益强大,这些芯片将产生极大的热量。而随着这些芯片温度的上升,硅的物理特性将发生变化,对使用的用户来说,就会出现频繁的死机现象,造成用户使用上的不便以及难以挽回的损失。对于桌面 PC 来说,较大的内部空
Consumers familiar with laptops may notice the phenomenon that laptop CPUs tend to clock slower than desktops of the same age. For example, at present the best CPU chip frequency has more than 1GHz, while the current mainstream notebook computers mostly in the frequency between 600MHz to 850MHz. One of the reasons is that the laptop’s cooling problem. Cooling problem is a very key performance indicator for notebook computers, cooling problem is not solved, the notebook will not be able to use. We know that these chips generate tremendous amounts of heat as CPU clock speeds continue to increase and as other controllable processing chips become more powerful. With the rise of the temperature of these chips, the physical characteristics of silicon will change. For the users who use it, frequent crashes will occur, causing inconvenience to users and irreversible losses. For desktop PCs, the larger the internal space
