CPU_FAN or W_PUMP?

[A47H]

I have a Corair H115iPro and was wondering whether to put the pump header into CPU_FAN or W_PUMP.

On the cooler’s manual it says to connect the pump to CPU_FAN, then to connect the 2 fans to the connectors on the pump, but the Mobo says to connect the pump to W_PUMP. I’m very confused...

My Mobo is a Asus ROG Rampage VI Extreme

pump needs to go on the pump header as that runs at 100% all the time, which is recommended for an AIO. Works fine with my H115i non-pro.

If you don't have a fan connected to the CPU_FAN header the motherboard will complain about it when it boots. It's basically a warning telling you that's there no CPU fan connected. You can disable this warning in the BIOS. When I build computers I just plug the cable from the pump the CPU_FAN. What you also could do, is to take a case fan and connect it to CPU_FAN and connect the pump to W_PUMP.

AIO with integrated fan hub?  Plug it into whichever header supports a higher amperage.

If the Corsair H115 iPro uses more than 1A, I'd go with the pump header and plug a case fan into CPU_FAN to keep it from complaining.  Probably be fine on CPU_FAN though.  Note you've got a H_AMP header is well good for 3A I think.

 

Edit:  Found a review that said the W-PUMP headers are good from 3A as well, but can't find official documentation confirming it.

Thank for the help.

So basically, what I should do is connect the pump header to W_PUMP, and a case fan to CPU_FAN. 

What do I use the H_AMP header for? I have 7 case fans btw. On the Mobo there is a CPU FAN, CPU OPT, CHA FAN 1-3, H AMP FAN, W PUMP +1 or W PUMP +2, and a EXT FAN. There is also a fan extension card, which has three fan headers.

Assuming H AMP FAN is just a more powerful header, i’ll Plug the radiator fans into W PUMP, a random case fan into CPU FAN, the case fan above VRM to H AMP, and the rest to fan extension and Channel fans.

I also saw this forum and some guy said to use CPU FAN for radiator because it’ll warn you if the pump fails.

PS I don’t know much about fans and stuff yet , as you can tell.

H_AMP would probably be good for a fan hub because of its amperage capacity.  Doesn't have to be just a single fan.  I'm sure it'll warn you about any failure on a header.  Pretty sure the pump plus two fans wouldn't go over the CPU_FAN's limit of 1A.  Think the fans are around a quarter amp each.  Either way, should work fine.

Thanks! The fan hub comes with a 5 pin connector, which EXT FAN has. Basically, EXT fan is made for the hub. Thanks for the help btw. I’m gonna stick with what I listed above.

I've had three different Corsair AIO's and the pumps are powered by the USB connector.  The only PWM connector is for the fan speed control which connects to the CPU_FAN connector.  

 

Not sure how different the H150i Pro or H115i are from your model, but on those, the USB provided all power and the fan header was just for speed control.
