I'm ordering my new computer tomorrow and just making small adjustments to the things I want, I plan on using this case. It has space for 3 120mm fans. I'm going to replace the fans that come with it with quieter/powerful...er, ones. The fans are located on the top, side and back. I imagine the top should be exhaust since heat rises, I'm just not sure about the other two. Also how can I tell what direction to face the fan when installing them so I know if its going to take in or blow our air? Lastly, I want to get some small fan to mount in the external 3.5" drive bay to blow on the RAM and keep it cool. I looked around NewEgg for something like that and can't seem to find it. It wasn't under Memory Cooling, and I looked through 300 or so fans on the site to see anything like it but no luck.
