4 pin fan splitter

So im building a pc with 7 fans inside it. 3fans from my liquidcooler and other 4 are just case fans ill be putting in. My question is I need to use a splitter and I have found a splitter that is 1 way to 4 fan splitter and I have 7 fans. So my question is if I buy it twice and I leave 1 cable...

I have only been able to find one 4 way fan splitter that didnt run on molex or as a hub, and the seller just canceled that on me. So does anyone know where I can get a 1 to 4 way fan splitter (4 pins pref)? Mobo only has 1 header, and the wires on my fans are too short to all be able to reach...
