My shop for individual PC systems: https://krotus-computer.de My hardware Discord: / discord There are many different cases. Often they only have 1 fan pre-installed in the front, but sometimes 2 or 3. In this video I test how many fans you really need in the case? Is it worth installing additional fans in the case or is it enough if the case already has 1 fan in the front? How do the temperatures of the graphics card and the processor change with the different number of fans?
