Do the fans, you've recently purchased, operate off the 3 pin header or a 4 pin header?

Although your board has 6(5 to be fair) fan headers:

You could run all 4 of your case fans off the fan headers apart from the CPU and water pump header but having them to sync up would/could pose as an issue. I would suggest buying a PWM splitter like this one or this and have all the case fans on it while the splitter itself is plugged into the CPU fan header so any variation of CPU temps will vary the speed of the case airflow.

Stop creating multiple threads!

If the fans are 3 pinned, they will be voltage regulated. You can forgo the PWM splitter since the PWM signal would cause the fans (apart from the CPU) fan to run at full speed.

You can connect the fans to the motherboard headers strewn across the board and in BIOS set each fan header to a desired RPM/voltage but please be warned, not all boards will offer voltage regulation on all headers.

Yes some boards can't manage 3-pin voltage-regulated fans on PWM headers and as mentioned they run at full speed.

But in that board's BIOS in BIOS>HARDWARE MONITOR tab you can select between PWM and DC mode and set fan speed through customizing fan curve graphs.
