I can’t get my Corsair HD 120/140 fans working on my motherboard. What am I doing wrong?

I am in the process of sourcing/buying parts for my first tower PC build. I currently have 3 Corsair HD120 and HD140 fans. Each set came with a six-fan controller hub thing. My motherboard is the Asus ROG Maximus X Hero (WiFi AC). I also have a Corsair HX1000i PSU. The case I’m putting these parts in (along with the other internal parts I have yet to buy) is the Corsair 750D Airflow Edition. I want to eventually replace the included fans with these HD140 fans and put two of the HD120 fans on the bottom after removing the modular drive cages.

All of the fans are rated at 12 volts and 0.3 amps power draw. I wanted to test the fans for their LED effects and air flow. The fans each have two cables, one for power (connects to the motherboard), and one that connects to the controller hub for the RGB effects. The controller hub has a SATA connection which I assume connects to the PSU via the SATA power cable that’s included with the PSU itself.

When I plug In the 24-pin power cable, all of the built-in RGB effects of the motherboard start. It looks nice and all, but I’m only interested in testing the fans at this point. I then plug in the fan power cable for one of the fans into an available PWM fan header and the other cable into the first slot of the controller hub. Then I plug in the SATA connector of the hub to the SATA power cable connected to the PSU. The PSU was turned on after connecting it to the wall outlet.

The fan controller has three buttons on it, one for fan speed, LED mode, and LED color. But when I press any of the buttons after connecting everything, nothing happens with the fan. No spin-up, no lights, nothing. Ive tried with an HD140 fan as well with the same results.

What am I doing wrong? I thought I just needed to put the connectors where they needed to go based on their connection type, plug the controller hub into the PSU, power the board up and test the fans. Is there a specific order I need to do things in?

TL-DR: Trying to test fans by connecting them to the motherboard, fans aren’t spinning up or lighting up.

For those interested, I plan on eventually getting a Samsung 960 EVO 1TB M.2 NVME SSD, an Asus Strix Gaming GTX 1080Ti OC Edition GPU, an Intel i7 8700k delidded and OC’d to (hopefully) 5.2GHz from Silicon Lottery, the Arctic Liquid Freezer 360, 32GB of PC3200 RGB ram from G.Skill, and an Acer Predator 144Hz 2560x1440 monitor with NVIDIA Gsync with a 1ms response time. I’m also using a 2 meter RGB LED strip from Phanteks for accent lighting (trimmed to fit, with an adapter for my Asus board since I’m not using a Phanteks case).


Thanks in advance for any and all advice!
 
Solution
You can try hooking up the motherboard with everything you need, hookup the fans and PSU, and start it by jumping the headers (you can google this).
I personally would just wait to build the system.

Yeah, that’s essentially what I’m doing. I just wanted to test the fans out but I didn’t have a way to power the fans on aside from connecting them to the motherboard PWM fan headers. The fan power cables don’t fit into the hub so I can’t just plug the hub’s power cable into the PSU and hope they light up. Do I need a jumper or something to be able to get the proper power to the fan headers?

I literally just ordered a jumper tool off of amazon. I think it’s highly unlikely that I got defective fans. Though it’s really fans I want to test at the moment. I’m fairly confident everything else will work as I’ve researched the compatibility of all of my parts. Thanks for the information!
