I have 6 Akasa AK-FN059 120mm Ultra Quiet Venom Viper fans, 3 intake and 3 exhaust (2 exhausting through top mounted rad). My motherboard is a
MSI Z97 MPower Intel Z97, it has 2 cpu 4 pin headers pwm enabled, and 3 system headers (4 pin but actually only work as 3 pin). For some reason, the board oddly detected the speed from 1 of the system header and not the other 2, this means it runs the fans at about 1000rpm minimum, so it can be a bit noisy for just Internet browsing and films etc..
Any ideas on what could be causing it to not detect these fans? It seems to detect other 3 pin fans fine.. If not, what fan controller do you guys recommend that will look okay and allow me to run the fans at the minium rpm, or even zero rpm.
