Airflow?

Lies...there should be about the same amount of intake as there is exhaust, some other people have their theories such as; more intakes, more exhaust etc. The common law is though to have an equal amount.
 
You should have more exhaust then intake in order to get the proper air pressure. When you have more exhaust then it will pull more air from the intake.

QFT.

You want the air to rush through. When it passes by everything is when it cools it.

If the air just sits there, the air will just heat up and not cool anything. Its logic.

Think like you have a pot of water.If you pass the pot of water over the flame of a fire quickly and don't let it sit there, the water in the pot will stay reletively cool.

If you put the pot in the fire and leave it there, the water will boil.

I hope that analogy works. :p
 
With low pressure in the case (more exhaust than intake) it is possible for dust to bypass the filter if there is any gap around drives, covers, etc. That happens in my HTPC's case (Antec Sonata) around the bay covers, since it only has one fan at the exhaust.
 
Negative case pressure can result in your PS over-heating (since most current PS are equipped with fan(s) to draw air from inside the case), due to stalled air flow through the PS. Your PS may overheat due to stalled air flow. If the PS auto-adjusts fan speed, it will sense high temps and force PS fans to run at highest/loudest speed.

I favor optimized front-to-back air flow configuration (no side vents) with equal-flow front intake and rear exhaust fans. If fans are not rated for equal flow-rate, the lower-flow fan restricts air flow. For example, a single Panaflo M1A will produce more air flow through the case than when combined with a 'silent' low-flow fan. If a single case fan is used, it should be used for front-intake fan to avoid negative-pressure in the case.

Cases with side-vents create alternate flow paths, resulting in lower front-intake air flow over your hard drives - resulting in warmer drive operating temps. Tape off those side vents for better uniform cooling of all components.

Other things to check for better case ventilation/cooler operation:
- Restrictive case fan grills.
- Restictive case front bezels.
- Restrictive filter media.
- Side-mount hard drive cages tend to obstruct air flow.

Hope this helps!
