Experts - I'm building a high end workstation utilizing the cooler master HAF 932 (In case your wondering, no I didn't get it because it has blue fans :)) and was wondering which way I should point my CPU fan (Artic Freezer i30). Since the case has what I assume is 2 inlet fans (side and front lower) and 2 exhaust fans (rear and top) I was thinking that the CPU fan should point upward toward the top exhaust fan so that it can draw air from both the front and side inlet fans. The alternative of course is to simply point it towards the front of the case but since its so high up it doesn't seem to get direct airflow. What are your thoughts? Upward or to the front?

Also since the case fans are 3 pin and not 4 is there any advantage to running them from the mobo (which has 8 x 4 pin fan connectors) rather than from the PSU? I know that the monitoring tools should report the RPM of the fans if they are on the mobo but that is about as useful as a chocolate fireguard if it can't actively manage the RPM.

Thanks Ganon - Out of curiosity may I ask why you think front to back as opposed to bottom to top? I'm leaning towards front to back but part of me thinks (logically) that since I have that huge fan on the side and the fan at the front lower that it should point downwards so that it can take advantage of that air being pulled into the case...
