So YOur CPU seems to be geting fresh air fomr Fan 1 (on your door case)
The rest of the mobo (and videocard) seems to have a curent, from Fan 2 (intake) to fan 3 (Exeaust) So that seems quite nice.
Here, downlaod the softwear speedfan on the site Free downloads encyclopedia - Softpedia, and tell us the tmeparature of your CPU, Hard drive (HD) and Ambient.
no....too much intake is pointless, the hot air would be 'stuck' in there....
by the way, you got nice temparature, no need o fmore fans or a etter setup. i'm kinda jalous! i love your case also.
I think everything is fine in your case, looks great.
also, her eis an explanation on why its good.
The intake fan 2 gives a curent from right to left (exits by the exaust fan 3) this curent brings in fresh air (cool) and as it travels, it becomes warm (to hot) and exits to the back fan. the CPU gets some really fresh air from intake fan 1.
My worry was that the CPU current who interfear with the curent right-to-left. but is dosn't seem a problem.
