A processor is not the only heat source in a computer. But the most solid of them. Therefore, special attention is paid to him. But modern video cards also have a specialized processor on board. He is also warming. And “overclock” video cards even more often than the central processor.
The first video cards with 3D accelerators caused us a lot of trouble with their “hot temperament”. Some video cards could work normally only the first 10 … 20 minutes after switching on. Continue reading
As a horizontal cable in modern SCS, a four-pair balanced cable is used mainly. It is known that for signal transmission in Ethernet and Fast Ethernet networks, only two out of four pairs are used. The remaining pairs are virtually idle. The technical characteristics of modern cables in terms of the NEXT parameter are very high (see Fig. 1), which allows the use of free pairs for transmitting analog and digital signals without any noticeable effect on the operation of the main application.
