Okay. I have been building a PC and it´s my first time. I all started very well but then I got to the Chassis fans. I have a "ASUS Prime B350-K" motherboard the chassis I have is a "Fractal design meshify c" which has two stock fans. I have bought two extra fans "Noctua NF-F12 PWN" so a total of 4 Fans. I have now found out that my motherboard only have 1 chassis fan connector and don´t know what to do? I would like to install all the fans. People say this is good: http://silverstonetek.com/product.php?pid=526&area=en does it make any problem that my stock fans are 3 pinned and my Noctua´s are 4 pinned?
