Fans, fans, and more fans. The Thermaltake Spedo Advanced Package comes with a ton of cooling. There are 2 120mm fans in the rear of the case for exhaust. There is a 230mm at the top of the case for exhaust and a 230mm intake fan on the side panel. There is a 140mm intake fan in front that was shown when the bezel of the case was off and also a bonus 120mm fan shown in the extras photos on the first page to place either at the bottom of the case or behind the mother board. I mounted mine as an intake behind the motherboard. There is also a multi-chamber cooling system that uses plastic dividers to channel the air better.
