Fan Xpert controls your fans based on a temperature sensor which sits on the motherboard under the CPU. This isn't such a bad way to control fans, but is focused on a single measurement. As soon as the CPU is loaded with work, the fans turn on and when your CPU is done, the fans turn off. It's not sensitive to ambient temp, internal case temp or anything else. If you would be doing something that stresses the GPU but not the CPU, then Fan Xpert can't see that.
With an Aquaero you can connect sensors to measure various temperature and construct a strategy with a simple drag-and-drop interface. For example a better strategy to control fans is based on coolant temperature, because when the water gets hotter, it means the fans need to spin faster. It's a much smoother way of reacting to changes in load. Here I show how I made a virtual sensor for the ambient-water delta, then I set up the rad fans to run between 600rpm and 1400rpm, and finally I made a controller based on this delta and set it to keep water temp at 10C higher than ambient air temp. The Aquaero then automatically controls the fans in order to achieve this.
