Vertical vs horizontal case temperatures?

[tom2u]

Somebody tested a vertical case and found that when they measured the temps when it was horizontal, there was almost no difference compared to vertical. But maybe it also helps pockets of warmed air to be expelled faster and there may not be a sensor measuring all areas of the case so why not orient everything vertically? Granted the wires if they come from underneath would be more of a hassle to deal with but once things are plugged in, its all good. You could raise it several inches off the ground as well and that would help against dust. And when I say vertical I mean nothing is mounted horizontally in the case: Hard drives are vertical, power supply is vertical, everything is vertical. Not that it would be difficult to do. Not like this where the 5.25" devices and power supply are horizontal. http://www.pcworld.com/article/2047082/review-maingears-shift-super-stock-z87-is-an-exercise-in-pc-gaming-decadence.html

If I'm understand your correctly, positioning the components horizontally or vertically will not inherently affect case temps, but rather positioning them in a way that influences airflow, for better or worse, will affect case temps.

I meant to say that even though the temps may not be very different its still a good idea to have vertical airflow because there are often pockets of heated air that the sensors are not measuring. Why ignore physics and hot air rising? The Mac Pro may be on to something (though their temps are horrible because their heatsinks/fans just don't seem to be working well but that could be easily remedies) by using vertical airflow. It may be interesting to try vertical layouts with liquid cooling as well.

So, yeah, like I said, positioning components horizontally or vertically will not inherently affect case temps. It's how your fans are set up and how the components are set up in relation to airflow. Most people have intake/exhaust fans at the front/bottom/side and exhaust fans at the top/side, allowing air to be moved in an upward direction. If you do the same type of setup with the case on its, the concept is the same.

In regards to liquid cooling, aside from case fans, most people position the radiator at exhaust fans. It's the same concept I described above.
