The solution depends on type of fans and type of speed control. Splitters are messy and quality is unreliable.

Don't know about your motherboard, but I think there is probably a current limit on fan headers (a max amount they can provide), so chaining a bunch of fans from a single header pin may not be the best idea. Most of the time I think you may be safe plugging in a couple of them, but be careful. One other suggestion is to hook up the extra two fans (with on on the motherboard header) straight to your power supply and have them run all the time.

2. Do not exceed 1 amp draw on your MoBpo header
