Creative Thermal Solutions:

• There are two 140mm intake fan on PC-A71F, The fan can output high air flow volume with lower RPM to push the cold air through the HDD rack.
  
  
• There is a 120mm exhaust fan behind HDD cage to draw the hot air out, and improve the air flow inside the chassis.the openings on the bottom of the HDD cage to allow the air to cool the HDD.
  
  
• The rear 120mm exhaust fan just next to the CPU, it can remove the hot air out fast and silently.
  
  
• There are vents on the PCI slots, provids extra cooling to graphics card.
