Phanteks Enthoo Pro Fan Hub Configuration

[canquillo09]

Hello all I know someone here already asked a similar question but I am struggling still to understand. I have a Z170 Pro Gaming Motherboard and my CPU cooler is the Noctua NH-D15. One of my chassis fans is not spinning and every fan is running full rpm. My goal is to be able to get all fans working, and be able to control their speed through the Bios. This is my first build so please take this into consideration. Thank you!

NOTE: Currently I have a SATA 12v power input in the power hub. Every other hub is empty except CPU FAN but that one is 4pin and I have my chassis fan (which is 3 pin) connected. Where do I go from here??
Another NOTE: I am using both CPU fans for my cooler. They are in CPU OPT and CPU FAN pins.

How many chassis ventilation fans do you have? And, are they all of the 3-pin type?

My thinking is this: you may not need to use that Phanteks PWM Hub at all. It is ideal for connecting many 3-pin fans to a single mobo header to achieve control. BUT your mobo has three CHA_FAN headers (enough if you have only 3 case vent fans) and they all CAN be set to control 3-pin fans.

So tell us how many case fans and their pin count. The two fans on the Nocuta cooler system are a separate issue easy to deal with - you may have them set correctly already.

Hello thanks for the help! I have two case fans, and what exactly do you mean by pin count? They are both 3 pin so 6 in total i guess.

By "pin count" I mean how many wires and pins coming from ONE fan. The reason I ask is that different control methods are required for 3-pin fans and 4-pin fans. So here's what you can do easily.

For the two 4-pin fans attached to your Noctua cooler system, plug one into the CPU_FAN header, and the other into the CPU_OPT header. I think you have done this already. They will be controlled by the same automatic system.

For the two 3-pin fans for case cooling, plug one into each of the CHA_FAN1 and 2 headers. They have 4 pins sticking up, but the fan connector will only cover three pins on each.

Now you need to go into BIOS Setup to configure the fan headers. See your mobo manual on p 2-6 to start. To get into BIOS Setup, turn on the machine and immediately press down the "Del" key and hold it down until the opening setup screen appears. Normally it will show you Easy Mode (p 2-7) and then you press the F7 key to get to Advanced Mode (p 2-8).

On the main menu across near the top click on Monitor. See p. 2-36. Scroll down to CPU Q-Fan Control - see item 2.7.4 on p. 2-37. This should be set to "PWM Mode" for your 4-pin fans, and lower down set the CPU Fan Profile to "Standard". Scroll down further to section 2.7.5 on p. 2-38, Chassis Fan 1/2/3 Q-Fan Control, and set this to "DC Mode" for EACH of your CHA_FAN headers. (You probably have to set each of these headers separately, and not make just one setting for them all.) Next item Chassis Fan 1/2/3 Q-Fan Source should be set to "MotherBoard". Then set Chassis Fan 1/2/3 Profile to "Standard". Now use the F7 key again to return to Easy Mode (p. 2-7) and use the F10 key (prompting note at bottom centre of screen) to SAVE and EXIT. This will same all those settings you just made and re-boot your system.

Those adjustments will set things this way:
Your two CPU cooler fans on the Noctua system will be automatically controlled by the mobo (using PWM Mode for the 4-pin fans) according to the actual temperature measured inside your CPU chip by a sensor, with details of the control strategy pre-set for you. The two case cooling fans will be powered and controlled automatically by the two CHA_FAN headers they are plugged into, using DC Mode (required for your 3-pin fans), based on a different temperature sensor built into your motherboard, and using its own group of pre-set parameters.

Thank you so much! Very well explained. Yes I already had connected the Noctua fans in the two cpu headers. I also managed to get the other fan working so now both of my case fans function. I will try to play around with the settings and see noise level and temp difference. Probably won't notice a big change in temperature. One again thank you very much!!

You're right about the temperature. The point of automatic fan speed control is that each fan control system (two - one for CPU alone, one for case and motherboard) has a temperature target, and it will adjust the relevant fan speeds to hold to that target. In your case, only the speeds of the case temperature (as measured by the Motherboard sensor) might change, because you already had the CPU cooler system set up properly.

Thanks for Best Solution.
