Case Cooling

From TPU Reference

When cooling a computer case it is best to keep negative pressure inside the case, this allows cooler outside air to be sucked in through every opening. Removing all dead patches of air with in the case. By removing all of the "dead air" within a case you drop the case temperatures on average by 5 degrees Celsius and when combined with air cooled components such as your CPU this will allow cooler CPU temperature.

The most effective fan setup is placing an intake fan in the front at the bottom of the case. This allows the hard drives to be cooled first. Having a side vent for the CPU and video card is beneficial as well. Output is best in the top back of the case under the power supply. Having a blow hole in the top of your case allows hot air to simply rise out of the case. By placing vents and fans in this manner you are able to remove a large amount of hot air. Cold air comes in through the front and side while hot air goes out through the top and back.

If you own a stock case made by Dell or HP or most other manufacturers your system is already using negative pressure in the case it is created by using a single output fan. The output is normally just the PSU cooling fan but some companies do add additional fans for output only. To improve temperatures in this style case add one input fan near the front and two out put fans (PSU included) in the top rear of your case.
