Do I need more fans?

well it depends how powerful are those fans,what components, and where the fans are. if the fans are placed in the back and front and thier only a cpu it should be okay. if theres more components or thier not in a good config get more fans.
 
It depends on the size of the case being used. A larger case like my 300r runs quite well with 2 intake and 2 exhaust (Its 3 exhaust, rad and case fan)
Smaller cases get plenty of flow from one intake one exhaust, more fans simply mean more noise.
