There are very limited options for those kinds of controllers. NZXT Grid is another. Your mobo has 1+2 headers, and its mITX mobo. The logic is that you have case with maybe 4 case fans slots anyway. And when you can connect 2-4 fans to single header, those are quickly filled. Most users use zones. Like one for intakes, one for CPU, one for exhaust. That way you can do it with just few splitters.
