It's only relevant when you have a completely PASSIVE computer case with absolutely NO fans whatsoever. People really need to ignore the entire hot air rising concept as all if does it cause people to try to factor it into their cooling systems and quite often go with a less effective configuration trying to accommodate it. Do yourself and everyone else a HUGE favor and NEVER mention or even think about hot air rising in respect to computer cooling. It will only mess you up and cause problems.
I respectfully disagree, Papa.
1. The lower intake at the front of the scout 1 x 140 mm together with the default 1 x 120 mm side panel intake is matched with the same fans top and rear in exhaust. If airflow is in balance, cool air being denser than hot air must be pushed upward. Vacuum effect.
Cool air in from the low points and out at the high points. That's Cooler Master's design, not mine.
2. Airflow not in balance will conflict with the above.
3. In theory, that flow can be altered by shifting fan positions, type, sizes, pressure, etc, to achieve a desired flow, but you would have to over power one side to compensate for the other.
4. The only analogy that comes to mind is that if your theory is correct, then a hot air balloon cannot fly on a cold & windy day.
5. Your criticism seemed pretty harsh.
