Thanks Dave! I don't know why they went with such a heavy airflow. I just ordered the setup I posted and will give it a try. I know there are adapters to go from 120mm to 80mm but I thought I'd keep it simple. The only disappointment is the response I got back from AC Infinity regarding the speed adjustment. Its not infinite but just has high, medium and low settings. I'll give it a try and if it doesn't work go with the smaller fan.
