Hey guys I just put in an extra front intake fan, by removing drilling holes in two drive bay covers and removing one drive bay cover inbetween them ( and obviously attaching the fan) I'm going to cut the two other drive bay covers( the ones with holes) in order to increase air flow. How ever I am not sure if the fan is actually drawing any air when I have the door shut. Firstly do you think it is or isn't? And if it isn't how can I can about fixing it. Thanks!
