The reason for only one RPM lead is so only one rpm signal going to motherboard. There have been times when more than one rpm signal to motherboard confused motherboard PWM controller and fans run crazy not knowing what the rpm really is. Two identical fans probably no problem. But if you are using different fans and/or they are not all spinning at same rpm then rpm signal is not a single rpm signal... I've ran 8 fans.. 4 different kinds.. on one pwm signal with no problems using single rpm lead to mobo.
There are many other PWM splitters available on the market. Many use only a single rpm lead.
Think of it as listening to several people reciting a poem to you.. if they are all reciting it in sync you can understand it.. if they are not it will become garbled and you won't understand the words.
