Question

Iron

Tell me where to find information on how to properly organize the cooling system (placement of coolers) in the system unit. Interested in information on different options for buildings. How should the air flows? (preferably in pictures).
Or is everything standard? - from below in front captures - behind from above blows out?

Answer 1

Coolers at the front and bottom should blow in air, at the back and top they should blow out.
At the same time, it is desirable that the tower cooler on the CPU drives air to the rear cooler, and the power supply is located below and takes air from outside. A cooler on the side cover will also help to remove hot air from the video card.

Answer 2

There are recommendations and a standard from Intel - Thermally Advantaged Chassis (TAC). Here, if you master cache-www.intel.com/cd/00/00/38/71/387155_387155.pdf

Answer 3

Well, if very briefly - the volume of air should pass and blow out excess heat, and not circulate inside making noise and leaving heat inside.
