Hello forum,
I recently put together my first build in the phanteks enthoo luxe.
The case has a built in fan hub, to which I have connected two front 140mm fans, one top 200mm fan, and the pump for a corsair h60. The fan cable for the h60's fan wasn't long enough to reach the hub so it is connected to a fan header labeled gpu_opt. The hub is connected to the cpu fan header.
The fans were making a lot of noise , so I went into the bios to change the fan speed, but only the h60 fan was showing.
This also caused an error showing up on each startup saying "gpu fan error" and forcing me to go into bios before startup. I set the gpu fan to ignore to bypass the error message since the temps were fine, but I would like to be able to monitor and control my fans.
Any suggestions?

If the other fans are 3 pin not 4 pin, you cannot change them in the BIOS.
Also, you need to keep the Pump fan connected to a chassis fan header on the motherboard or you WILL BURN THE PUMP OUT FAST. The Fan should be connected to CPU_FAN, NOT THE PUMP.
That Hub should be connected to a chassis fan header, NOT THE CPU HEADER.

The pump needs a steady 12v, you don't want to reduce its voltage using your fan hub or the motherboard's fan controller. Feeding it less than 12v will drastically decrease the water flow and may damage the pump over time. I'd hook the pump into the PSU directly.
Each one of your motherboard's fan connectors can only read the rpm from one fan. That is why you are only seeing one fan from the cpu fan header. You should hook up the H60's fan to the cpu-header all by itself. You should hook your other fans into the sys fan or chassis fan headers on your motherboard (You can also hook the fan hub into one of these but they will all be controlled by that same single header). Depending on how many fan headers your motherboard comes with, you may be able to control all the fans individually using the motherboard headers (or hook up the front two together on a single header using a splitter).

The pump should not be direct to the PSU as it fluctuates based on CPU load. It needs to be connected to Sys_fan header. My understanding is that the pump should always run at full speed regardless of CPU load (these pump motors are not designed for variable voltage input - they are designed for constant 12v). The rad fan fluctuates with CPU temperature/load (hence why it should be connected to the CPU_FAN header). You can connect the pump to the SYS_FAN header but you'll need to make sure the SYS_FAN header is set to constant full-speed in the BIOS because you don't want the pump to receive less than 12v (or it will be damaged over time). You can also hook the pump to the CHA_FAN header, again as long as you set the CHA_FAN control in the BIOS to constant full-speed. Hooking it directly to the power supply guarantees a constant 12v regardless of motherboard settings (but you lose RPM monitoring capability).
OostavOo - Depending on your motherboard you can hook your fan hub into either the SYS_FAN or CHA_FAN header. In the BIOS you should be able to create a fan profile for that header and that profile will control all the fans connected to the hub at the same time. There is only one tachometer (RPM) pin on the mobo header so you will not be able to see each individual fan's RPM - it depends on how the hub is wired as to which fan's RPM is reported. However, all the fans connected to the hub will be speed-controlled by the header's fan profile you set in the BIOS. Does that make sense? If you have more questions please let us know what motherboard you have.

I already changed the fan setting in the bios to see if it did anything, but I wasn't able to hear a difference.
My mobo is the Asus z97-AR, and if I remember correctly, it doesn't have headers labled Sys_fan, only Cha_fan. I'll check again in the manual but is there a diffrence between the two? I assumed it was just a diffrent name for the same thing.

Yeah your board has lots of fan headers. This means you can hook each fan up individually or use the hub. The case fans should be connected to the CHA_FAN headers and/or you can also hook the hub up to one of the CHA_FAN headers. It looks like each of the CHA_FAN headers can be individually controlled so that means that each of the CHA_FAN headers can be controlled and monitored using the Q-FAN control in the monitor menu of the BIOS and also using Asus Fan Xpert software. Just make sure whichever header you use for the pump is set to "Turbo" (which means full-speed).
