    CFM = Cubic Feet per Minute. It's a measure of air flow.

    dBa = Decibels. It's a measure of the noise level.

    Well I would be fine if it was as quiet as the fan I have now, but Im just wondering if their any consequences of picking a fan for the front of my pc to fast or equal speed. Because if the fan I purchase for the front of the case is to fast the fan at the rear will have trouble shooting it out wouldnt it? And wouldnt that cause heating problems.

    that's basically what my case is like.. cept there are 2 fans in the front intake... one in the bakc like yers .. and one on top of hte case.. exhaust... works real well for me..

    they're all the same speed of course... I don't think I need to add any more fans because it's air circulation is perfect

    You might want to put a 92mm 52cfm or better on the bottom front like in the diagram if you have the space. If not, a good 80mm will do nicely. Also upgrade the back rear fan for a high cfm one. Panaflo works for me. make sure you cut a clean opening for the bottom front, and clear that opening in the back. I know it has those little holes so get a dremel or a pair of tin snips with the yellow handles to cut it. Also get a metal file or sandpaper to sand off the rough edges so u don't rip a piece off your fingers or hands. The main objective is to get clear air flow thru the case. Also tie up those cables and wires. Try and tuck em neatly and away from the airflow.

    You get that done and trust me, that case will be mighty cool :2cool:

    Maybe you might want to add a blowhole too.
