Hi guys. Im new to system building. I just got a thermaltak corev71 tower. I was curios on how to set up the best airflow for the fans. I have front fans pointing in. The rear pointing out and on top I dont know if I should have those fans pointing in or out. I might install fans on the bottom facing up too. But I dont know if that many fans are necessary. Once the system is complete I plan to do some miner ocing.
