I'm going to build a custom-desktop from the parts I am going to buy. If I remember correctly, I think that the parts itself include fans that will cool off the system. (CPU has a heatsink + fan?, while graphics card has it's own dedicated fan.)
Is it necessary to purchase additional fans for the system or will it be fine, considering how I will not be overclocking the system?
Specs:
CPU: AMD Athlon II X4 630 2.8GHz
RAM: Kingston DDR3 2GB
Graphics Card: Sapphire HD5770 1GB
Motherboard: ASUS M4A87TD or MSI 790X-G45
Power Supply: CORSAIR CMPSU-550VXCN 550W
Case: NZXT M59
Hard Drive: WD Caviar Blue 500GB

As you can see in the diagram below, the normal airflow of a computer case is "pulling" cool air from the bottom of the front to extract the warm air with pressure through the back of the case. So either you should install an additional fan at the bottom of the front, or at the back somewhere around the power supply. But, my computer i.e. has no additional fans. It worked fine without them. My advise for this situation is to test it without additional fans and if ou recognize some temperature difficulties add at least one.
