The only one you really need is the cpu fan.
You can fit and control other fans if you want, but for the motherboard
to control the fan speed the fan header must have four pins.
You might want one or more system fans to blow air in or out of the
case. Suggested fan headers for these will usually be labelled cha_fan
(chassis fan)or sys_fan (system fan). A fan to cool your hard disks is a
good idea. It is possible to control and/or monitor your PSU fan if the
motherboard and PSU have suitable connections.
If there are too few fan headers you can always buy molex to fan header
adapters. You can leave fan headers unused.
If you want independent control of fan speeds you can get variable speed
fan controllers such as the Fanmate 2 http://www.zalman.co.kr/Eng/product/...ad.asp?idx=206
