Motherboard fan port issue.

[ravic]

Hey guys,

I have a Corsair 460x RBG case with a ASUS TUF Z370-PLUS Gaming Motherboard and a Corsair H80i V2 Cooler. My issue is that I only have two fan CHA_FAN ports on the motherboard yet I have 3 front fans to connect. Currently I have the Cooler set into the CPU_FAN port and the bottom case fan in the AIO_PUMP port. The top and middle fans are both set to 1500RPM according to the BIOS and the corsair link program. The bottom fan however is only set to 950+RPM and I cannot change this. I have tried to swap the AIO cooler fan (bottom fan) that is connected to the CPU_FAN (corsair cooler) around and when I try to alter the speed of the bottom fan it says it is at 1500rpm but it still is slower then the top and middle fan.

Is there anyway to fix this with the current setup or will i have to swap out the motherboard or purchase something that can connect the bottom fan to the motherboard to control the speeds. Or is my bottom fan perhaps faulty.

Sorry if the wording confuses you. Thanks.

You can use a splitter.

Usually you can put two fans on a header and sometimes three.

You just can't go over the maximum amps the MB allows. Many times this is 1 amp.

So if it's one amp and your fans draw lets say .3 A you can put 3 fans on that header.
