Hey gang, I have a very big SuperMicro case. It has tons of fans in it. My question is, in the back along one side are slots for airflow. Would it help increase or decrease case cooling if I covered the slots to let more forced air get moved out by my YS Tech fan and power supply blowing air out ?? I have 3 fans sucking air in and 2 blowing out, one stock 80 mm and one hipo 60 mm ys tech ??
