Systems of old are able to function optimally with passive cooling methods, but the systems of today are faster more power and run at hotter temperatures, so active cooling is required for them. Faster and more power components generate immense amounts of heat while they are in full operation, because of this reality; they are unable to rely on natural methods of cooling. PCs of today require an exhaust fan in order to prevent it from overheating.
Your computer can use up to five fans to vent the hot air from the system, while pulling cooler air into the case; other components have heat sinks which are used for absorbing the heat. Just like any exhaust fan whether commercial or industrial that you might find in the bathroom or attic, it should have a high CFM rating, low sound levels and adjustable RPM's for flexibility.
Case fans are used primarily for cooling the air in and around the system case allowing warmer air to pass through and out of the system, the most heat susceptible components PSU and CPU are cooled by their own fans which removes the heat from these components. The GPU and motherboard chipset typically requite their own fans, whereas the hard drive, CD/DVD drive and expansion slots do not require cooling, but can benefit from it.
The best exhaust fans for your system feature rotating blades and blower wheels that shifts air with little to no sound, just like your other PC cooling devices, it's bearings and motors should be rust proof allowing it to function without generating much heat of its down.
