Computer Cooling
Introduction :
Computer cooling is the process of removing heat from computer components.A computer system's components produce large amounts of heat during operation, including integrated circuits such as CPUs, chipset and graphics cards, along with hard drives. Overheated parts generally exhibit a shorter maximum life-span and may give sporadic problems resulting in system freezes or crashes.This heat must be dissipated in order to keep these components within their safe operating temperatures, and both manufacturing methods and additional parts are used to keep the heat at a safe level. This is done mainly using heat sinks which dissipates heat, fans and with some other technology.
case cooling
A good PC Case will provide good heat management with addition fans support.,If the air around CPU is too hot then best CPU heat sink is useless. The hot air obviously needs to be evacuated from the case. All computer cases come with a fan pre-installed in the power supply; if this fan isn't sufficient, you need to install an additional fan. Acrylic cases may look better but they will not cool as well. Aluminum has slightly better heat transfer characteristics than steel (the two most commonly used case materials) but either material will work fine.
Case Materials : Steel Cases
Thermal Conductivity: Moderate
Aesthetic Appeal : Low
Cost : Low
Case Materials : Aluminum Cases
Thermal Conductivity : High
Aesthetic Appeal: Moderate
Cost : High
Case Materials : Acrylic Cases
Thermal Conductivity : Low
Aesthetic Appeal : High
Cost : Moderate
Most manufacturers recommend bringing cool, fresh air in at the bottom front of the case, and exhausting warm air from the top rear
case air cooling types :
- ATX case cooling
- BTX case cooling
- fan duct case cooling

So important point is airflow .
With a positive-pressure system , the inside of your case will stay cleaner because the only air entering the case will be filtered and the extra air that isn’t exhausted by the exhaust fans will blow out through cracks and vents in the case.
For a negative air pressure system, the goal is to have more air being forced out of the case than is being forced in. With a negative pressure system, the vacuum inside the case will pull dirty air in through those same cracks and vents. A negative pressure design however will result in better cooling because it keeps a constant stream of air moving through the case at all times.Remember that air is usually exhausted through a top-mounted blowhole fan and by the rear fan(s). This leaves the front and side for intake fans.
