With my set up and the fan at ~60%, one would assume I could leave the case side on, correct?Well, all gfx cards should run at stock speeds without requiring any extra cooling so you should be fine. Im running with a 14cm intake fan, 12cm exhaust, 2 side 12cm fans and a powercolour heatbuster. Befor changing the thermal paste to arctic silver 5, it used to reach over 70 C. Now it peaks at 68 C @ 700mhz with the fan at a lower speed too.
