I disagree with some of the answers above.
Start from here: a true 4-pin fan header operating in PWM Mode can NOT control the speed of any 3-pin fan. Likewise, any true 4-pin fan HUB that operates that way cannot do this control either.
Your case comes with three 3-pin fans. You have listed on pcpartpicker four additional Corsair fans, all of them 3-pin style. Your post says you plan to actually use six fans for case ventilation, so there's an extra we'll ignore. The main point is this: you can NOT control ANY of those fans from a 4-pin PWM Hub such as the Silverstone unit you plan.
However, there is a good way to do what you want. Your mobo has three SYS_FAN headers (see manual, p. 46) and even though they have four pins, they are NOT 4-pin headers using PWM Mode, so they can't be used with that Silverstone Hub anyway. In fact those three headers operate only like 3-pin headers in Voltage Control Mode (with a useless 4th pin) and that is exactly what you need to control all your 3-pin fans! The only thing missing is how to connect six such fans to three headers. You can't do this with a Hub - there is no such thing as a 3-pin hub system. But you CAN do this with 3-pin Y-splitters like this:

There is also a version with 12" long output cables.
Buy three of these and use one on each of your three SYS_FANn headers to convert them to accepting two fans each. That way you connect six 3-pin fans to three mobo headers that ARE designed to control 3-pin fans. Voila!
IF you think you need more than six case fans (I doubt it!), you can buy a splitter with three output arms (although it is actually made for 4-pin fans) like this:

You can always plug 3-pin fans into 4-pin male fan connectors, so that would work to connect three 3-pin fans to one 3-pin (or 4-pin) fan header on a mobo.
Mobo fan headers can power and control two or thee normal case vent fans such as you plan to use without straining them.
For your CPU cooler its website and manual do not make it clear how both its fans are to be plugged in. But they ARE 4-pin PWM type fans, and the mobo's CPU_FAN header is a true 4-pin design using PWM Mode, so you should have no problem. The cooler's fans may be wired so it only needs one connector to the CPU_FAN header, or it may have two separate connectors that need a 4-pin Y-splitter. If that is the case, I expect one is included with the cooler. Worst case, you need a splitter and one is not included, so you have to buy one, but I don't expect that.
