Need Help With Connecting Fans

Level 11
Hey everyone,
I am building a new PC, and I need help please,on which would be the best header to connect the fans to on the mother board. This PC will be water cooled with hard line tubing. I have 2 360mm radiators w/ 3 fans on each rad. The 7th. fan is the exhaust fan mounted at the rear of the case. I also have an EK 011 D Distro plate with a pump on it.
I don`t know which header to connect these fans and the Distro pump to, and what type of hubs or splitters I need. The Lian Li PC case and fans came with hubs, so I don`t know if these are all I need. The fans are ARGB too. I`ll give all my PC specs below. Thanks all.

Personally I connect my pump to the wpump header and set it to a fixed RPM. You don't usually need variable pump speed, just enough to keep everything flowing based on your loop's restriction and beyond that higher speeds don't buy you cooler temps. Fan speed matters far more.

Ideally you would use a temperature probe in your loop and use the water temperature to control fans speeds. That way when you get small spikes in activity you don't get fans ramping up and down. Water cooling easily absorbs those small spikes so you really only need the fans to ramp up when under sustained load(and thermal output).

If you're interested Jayztwocents has a recent video on some open source software that can control fans based on more than one input temperature. So if your rad fans are cooling both your CPU and GPU you might want them to ramp up if either of those components gets hot. I haven't tried the software myself but the potential to use multiple sensors is intriguing.
