All the reviews and including Abit site noted that Abit KT7TA series include a chipset fan, plus an extra pci usb controller. If your motherboard don't come in a retail case or with a chipset fan, then you have to question if it is genuine.
Abit puts fans on both KT7A and KT7 boards. My suggestion is to put a little beter fan and heat sink on it. The fan on mine started making noise after about a month. I had another fan so I replaced it. It works fine now.
