CJC1055, what size fan is that on your side panel? For some good advice, make sure you slightly have more exhaust. Because what happens is, when the air from your intake hits your mobo, it takes heat away. If you dont have proper exhaust, then that hot air stays in your case. Witch results in giving the heat back to your system.
Im guessing you have a exhaust fan at the rear of your case. I suggest putting another behind the other. Stacking them. Make sure you have good fans, another thing, make sure they are both the same fan. So they work at the same rate.
