Question

Iron

Should the lid on the PC be open or closed for better cooling?
In Google to meet completely opposite opinions !!!

Answer 1

Closed for sure!
The coolers provide a DESIGNATED circulating air flow, but when open, they circulate heat around the system unit in a chaotic manner.

Answer 2

It depends on which building and how the air flows are organized there . In some cases, it really is more beneficial to remove the cover.
Conduct an experiment, monitor the temperature with the lid closed and open.

Answer 3

Thermodynamics:)

Answer 4

If someone designed the cooling in the case (the wires do not stick out at random, but are laid aside and connected so as not to interfere with the air flow, there is a fan for blowing in fresh air and blowing out hot air, then when the lid is closed, air circulation contributes to a better discharge heat
If krivoruko left everything inside, then with the lid open it might be better.

Answer 5

air movement at speed will always provide a better temperature reading than gravity
