Can Reducing Airspace in a PC Case Improve Cooling Efficiency?

[nution]

I had a question and I figure you guys are the best for the task. I was wondering if theoretically you had a standard computer case, would you benefit by reducing open airspace in the case?

Lets say just for example you could place a cube inside the case that doesn't touch anything, it just reduces the airspace. Would the same cfm of airflow now help better cool the components in the case? Since it is not wasted on dead space inside the case?

Lets take it further and assume you could make an enclosure that just sits like 2cm over the components, in a closed air case of course, except you have the same cfm going in and out of the case? Would that increase cooling efficiency since the same bulk of air is now passed over directly and fully on the components then right out? Instead of the normal case, where the air may more loosely pass over components and the air temp has more time to rise since the standard case doesn't really effectively cycle air that well. I appreciate any insight to this or thoughts you might have.

nution,

I think you are over-thinking things. You could achieve far better results by simply lowering the ambient air temperature, going to a water cooled system, or increasing the air flow through the existing case.

You might want to play with this:

Anyway, good luck.
