Server fans: what they are, how they work

Server fans play a key role in maintaining the temperature at an optimal level. They operate at high speeds to ensure sufficient airflow within the server system, thereby cooling it. Most server fans are designed to operate at different speeds, which significantly enhances their efficiency. This means that when the server system is under load, the server fans operate at higher speeds to increase cooling, and when the load is light, the speed decreases. The main function of server fans is to ...

Article about vertical wall-mounting of servers

An interesting solution for home laboratories, small test rooms or maintenance-free points where 1-2-3 pieces of equipment are placed, and every square centimeter is worth its weight in gold I often came up with the idea: why not place servers vertically, because if you do not have a special server rack, but have a 1U-4U machine, and even a full length of 655 mm, then this bandura will take up the entire room, the entire table or rack.

With the advent of multi-core processors, it became clear that the more computing blocks, the better, but only until marketers stepped in and pided one CPU into ten sockets with ten cache options and ...
