[QUOTE="audioholic, post: 6816838, member: 549629"] This is a common mistake when adding fans to a system. A fan only displaces so much air, measured in cfm. Say you have 2 pushing cold air in, and 2 pushing hot air out at the other end. Each fan moves 500 cfm. 1000cfm pushing air in, 1000cfm pushing air out. Total air displacement, 1000 cfm. But, if you have all 4 at one end or the other, all pushing or all pulling, with 4 equal sized holes at the other end of the enclosure, the total air displacement would be 2000 cfm. In other words, having a fan pushing air in will not double the output the fan ******* air out. And their displacements are not cumulative. Having both pusher and puller fans doubles your voltage draw (and noise), while giving no noticeable gain over having half as many just pushing or pulling. [/QUOTE]
