I am building my first pc using a 780T Corsair case and Asus ROG Z270E Mobo with a Cryorig R1 Universal cooler. I have 5 Corsair AF 140mm LED Be Quiet fans and 2 Corsair 120mm LED Be Quiet fans used as case fans. I would like to connect all 7 fans to the Mobos headers. I'm wondering if I can use a 3-way fan splitter to connect 3 of the 140mm fans to one header? Is this safe, and can the header handle the amps? Also, if this is possible can I control the fans using bios?
