It just so happened that with the arrival of spring, my servers began to heat up more and more and overall performance in general began to drop significantly. Upon closer examination, it turned out that hot air from computers is re-sucked inside and causes it to multiply. If you have a lot of free space around, perhaps this is not so important for you, but I have very little space. So the idea came to me to use smart computer cooling by removing hot air outside the space in which the computer is installed. This is probably a good way for miners. The processor and graphics card, especially the RTX3090, get very hot and give off heat to the environment. Thus, the air around the computer heats up and then is sucked in again and again passes through the radiators of the processor and video card, heating up even more. This is a significant cyclic heating of the computer. The method proposed here allows you to lower the internal temperature. Warm air can be discharged into the supply and exhaust ventilation system or, simply, away from the server (s) installation site.
