Power supply Fans
The power supply fan (PSU) works in two ways; it removes warm air from inside the air and simultaneously keeps itself from overheating. Some PSU have two fans one large and one small. The larger one is in the bottom to remove case air and the smaller one is placed at the back to drive away the warm air at faster rate.
CPU fans The CPU fans or the heat sink fans are designed to keep the processor at a certain defined temperature. And prevent it from getting heated. In latest technology, CPU coolers have highly heat conductive copper and competently designed heat sink surface air that give out heat in a more effective manner as compared to standard heat sinks.

But nowadays we find some of the modern cards that are designed for gaming and 3D graphics obviously require their own dedicated cooling fans. Those high powered cards, found to produce more heat need more efficient cooling system.
