If you want to control multiple you can either get a fan hub for 4 pin fans or just connect the pwm controller in paralell and still suply the power trough this hub so you dont put to much pressure on that single fanhub output on your motherboard, or just split it up in multiple fan outputs. The PWM Hub in the case is designed to do this: it takes the PWM signal from one mobo fan port and it takes power from a PSU SATA power supply connector, and it uses those to create six 3-pin fan ports for you to connect fans to. Downloading the fan hub manual indicates that I should be able to plug in a micro 3 pin female to a port on the hub and voila. So I am using MSI's smart fan utility in the BIOS, and while that dictates fan speed based on motherboard temp, it does it for all 6 additional fans having them run at the same speed, which is how it is supposed to work on this arrangement--the FAN 1 header on the hub sets the speed for all of the other case fans. On my pc (Asus TUF X570) the fan hub works flawlessly. 1. The RPM signal is so we can see how fast the fan is running. 2. More heat means more PWM signals means more fan RPM. The PWM control on most motherboards does not use RPM to control fan speed. How do I connect motherboard to RGB fan hub. To connect the fan hub to the motherboard you will need to plug the four pin fan cable you can see on this pic (the one on the right, with the pointing arrow saying "Going to chassis fan 2 header") into a case fan header on your mobo. Then connect that to the first controller port by clicking on the light bulb icon with the A1 next to it. Depending on the connector - and I think that Gigabyte's z390 boards are using the same connector as Asus and MSI - it should be possible to get an adapter to control the RGB Fan Hub. OK, now that tricky bit is done, we can begin changing the LED modes and individual LED colours! How do I connect motherboard to RGB fan hub. The fan connector will have two guides (1) and these will need to line up with the tab (2) that is on the motherboard fan header. Next, press down until the fan connector is fully connected to the motherboard header. The fan will function normally no matter type of fan header is used. They only use heat and percent of PWM signal. This will add the fan into the top left-hand corner, next, we click on the light bulb icon of the added fan. I can tell you that Gigabyte's software doesn't do anywhere near what you can do with iCUE tho. As a little gimmick? C. Thermal Sensor Cable: attach the cable's connector end to the surface of other parts within the case to sense the temperature of the parts, and use MSI Dragon Center or the built-in fan curve in the hub to control the speed of the fans connected to the Hub. The fan plugged into hub's fan-1 header sends RPM signal to motherboard. The motherboard is not a power hub or a fan controller, the fan outlets are a convinience, nothing more. It comes with a preinstalled rosewill fan hub and a switch on the front to control fan speeds. You would need to use a Lighting Node Pro and an RGB Fan Hub. My conundrum is how can I connect to fan hub to the motherboard for aura sync to function.
