Hi community. I need some help with fans. My plan is to put a Phanteks PWM Fan Hub Controller in my build to control fan RPM. I was just watching this video and the Phantek Fan Hub is suppose to connect to the motherboard CPU header instead of the case fan header. If I plug that cable into the CPU fan header then I won't be able to control the CPU heatsink RPM. How would I go about this situation in order to be able to control both CPU and case fan RPM?

It can connect to any fan header.
Modern MoBos typically have two PWM Fan headers ....so you can connect two fans from ya CPU cooler to CPU header
-Z87 MoBos typically have the 2 PWM CPU Fan Headers and a number of 4 pin CHA fan headers that are NOT PWM
-Z97 MoBos typically have the 2 PWM CPU Fan Headers and a number of 4 pin CHA fan headers that are PWM but can be operated on both 3 DC Voltage or 4 pin PWMfans.
The Phanteks PCB works with either.
-If connected to a PWM Header, you can connect up to eleven 3 pin fans, but if you have more than 6 you will need to connect the SATA Power Connector
-If connected to a DCV Header, you can connect up to around 6 3 pin fans, but if youcconnect the SATA Power Connector, you will lose speed control. This should not be surprising as DC Voltage control varies the voltage from about 5 to 12 volts to control fan speed. If you connect a constant 12V power source, they will run at 100% speed
Here's what I have (Z87)
Channel 1 (PWM)
CPU Header => Water Pump No. 1
CPU_OPT Header => Water Pump No. 2
Channel 2 (DCV)
CHA_1 Header => PCB No. 1 => (5) Phanteks SP140 Case Fans
Channel 3 (DCV)
CHA_2 Header => PCB No. 2 => (6) Phanteks SP140 Fans on 420 (3 x 140mm) Radiator
Channel 4 (DCV)
CHA_3 Header => PCB No. 3 => (4) Phanteks SP140 Fans on 280 (2 x 140mm) Radiator
There are 4 separate fan curves controlling the speeds in each channel via Asus FanXpert Utility.
In your case, I would connect your two (assumed) CPU Cooler fans to the CPU and CPU_OPT headers or to the CPU Header with a cable splitter (you get 2 with the PCB).
Then I would take the chassis header and connect it to the PCB and use it to run all ya case fans (up to 6)

OK I'm not too experienced with fans so I only understand a bit of what your explaining.
Let me just lay out some information and maybe it will help:
This is my build. The case I have is the NZXT H440. That means I don't have any optical slots so I can't put any front panel fan controllers. NZXT includes a fan hub in the H440 but the problem is that it is directly connected to the PSU meaning you cannot control RPM. Since I don't want my fans running at 12V all the time I wanted to get a fan hub. To address the issue I went with the Phantek Fan Hub. Unlike the included NZXT fan hub it connects to the motherboard and PSU, not just the PSU meaning I have RPM control. Now the problem is that I have to plug the Phantek hub 4 pin connector to the CPU heatsink header on the motherboard if I want to control the case fans. This short video clip explains why Phantek Fan Hub is suppose to connect to the motherboard CPU header instead of the motherboard case fan header. That means the Hyper 212 EVO heatsink I have chosen will not have any power to run since the CPU header on the motherboard is occupied by the Phantek fan hub. Basically, I want to be able to control both the CPU and case fans and I do not want either of them to run at max voltage. Where would I plug the 212 EVO on the Z97 motherboard if the Phantek fan hub is going to be occupying the CPU fan header?

I have done multiple Phanteks builds, I know how it works; Joanne is getting it half right. Forget the video ... 
She had the case for a cupla days and did an unboxing video, I have had 3 Hubs, running 4 separate control channels since October
The hub is a single channel device..... you are NOT going to have fans spinning at two different speeds coming out of that hub ....it's 1 input and 6 outputs .,....what comes in the one input goes out on all 6 outputs.
YOUR 1st PROBLEM IS CONNECTING THE PCB TO THE CPU HEADER if you want your case fans and CPU fans to be controlled differently
YOUR 2nd PROBLEM IS ASSUMING YOU WILL CONTROL ANYTHING .... Your MoBo will do all the controlling.
1. Connect the Fan on the Hyper 212 to the CPU header..... DONE. leave it alone
2. Again, most modern motherboards have a 2nd CPU Header, usually called CPU_OPT.
a. If you have that 2nd CPU header, connect as follows:
CPU_OPT Header => PCB => All case fans.
If you do not have more than 6 case fans, YOU DO NOT NEED THE SATA POWER CONNECTOR
b. If you do not have a 2nd CPU fan header , then connect one of the Chassis Fan Headers on the MoBo to the Hub. Then connect all your case fans to the Hub.... Done
The controller hub is designed for 3 pin fans on the output side. It is designed to take PWM or DC voltage imputs from your Motherboard.
So ....
1. CPU Header => Hyper 212
2.a CPU _OPT Header => Fan PCB => All Case Fans
or
2.b CHA Header => Fan PCB => All Case Fans
Each header can handle only 1 amp.....Phanteks fans are 0.14 amps so 6 x 0.14 = 0.84 amps < 1.0 amps OK
If tour fans draw more amps makes sure that you don't draw more than 1 amp total
2.a CPU _OPT Header => Fan PCB => All Case Fans .... connect the SATA power cable if have more than 0.85 amps ..... not needed if you have less
2.b CHA Header => Fan PCB => All Case Fans .... can only use 6 fans or whatever uses < 1 amp. Connecting 12v power will remove speed control.
Your Motherboard BIOS or Fan Control Utility wilol control fan speeds based upon how you program it.

Makes sense. Just one thing, what is PCB?

His slang abbreviation for Phanteks Control Board.
The one thing mentioned, of which you MUST take particular note of is the fans themselves. A typical fan header, either cpu_fan or cha_fan has about 1amp max current. That's 12w. Most mediocre fans will draw upto almost 1/2 that, so recommended fans on 1 header = 2. While the PCB can handle upto 6 fans off the header, that's for quality fans like the Phanteks and Noctuas which pull about 0.09a - 0.15a, (1-1.5w) so 6 is safe.
Might want to take a close look at your fans you plan on using and start doin some math, before hooking them all up to 1 header. As said, 0.85amps should be the limit, or 10w, or you'll be shopping for a new mobo if you start burnin out headers.
Leave cpu_fan for the cpu. You could use it, and power the cpu fans from the PCB, but that would mean cpu spins same speed as case, and if you forget to turn it up 1 time... Well that could mean a new cpu too, you just fried the old one. So, leave it alone, don't use it for anything other than cpu fans, and let the pc worry about temp regulation.

Does PCB just mean the Phanteks fan hub?
My plan is to use NZXT's included [url=http://www.nzxt.com/product/detail/141-fn-v2-performance-case-fan.html]FN V2[/url] case fans. The case comes with 3x120 front intake and 1x140 back exhaust. I plan to buy more for the top exhaust. I'm not sure whether to go with another 3x120mm or 2x140mm. I was also thinking some Phantek fans as well. What do you think? I don't know anything about fans or wattage consumption so I was hoping you could direct me.
My second plan is to sacrifice fan control. As someone new to computers I didn't realize fans could go so in-depth. I'm becoming more apprehensive of buying the fan hub since you mentioned burning out an entire motherboard. I might just dodge the hassle and use the included fan hub. Of course I won't be able to control anything but at least I won't have it connected to my motherboard. I will probably just stick with the included fan hub. :/
Two other question. Is my build safe and capable of having my fans running at max voltage and RPM all the time? And should I just look for another fan hub instead of Phanteks?
What happens if I plug in the SATA power connector? Will my motherboard burn out?
Also, I said this in reply to another user and I'll use it again:

See above
Phanteks 140mm fans have the best performance / noise ration on the market...and at $10, hard to say no.

You can't burn out an antire MoBo..... yoiu can blow a header but you have lots of those. You are in a comparable position of having a 500 pound hoist and wondering how many 50 pound blocks you can pick up .... really doesn't matter iof you have 4, 5 or 6 blocks when you can lift 10. You have between 5 and 8 headers on your MoBo. These is no issue here. I have 15 fans on my rig controlled by 3 headers
It's just math
3 x 120mm = 3 x 0.16 amps = 0.48 amps
1 x 140mm = 1 x 0.18 amps = 0.18 amps (link dont work, 0.18 assumed)
2 x140mm Phanteks = 2 x 0.14 amps = 0.28 amps
Total = 0.94 amps so you could have every fan on a single header w/o issue
or....
CPU Header => Hyper 212
CHA_1 => 2 new two Phanteks w/ 2 way splitter
CHA_2 => Rear Fan
CHA_3 => Front fans

It would really be great if ya posted ya MoBo model and number of headers so we wouldn't have t 0guess about possible options.
As i said, the only reason to use the SATA Power cable....
1. If you have more than 1 amp you will need the power
2. You are using a PWM header
3. The cable can NOT be used on a DC chassis header (i.e. Z87)....all fans will run full speed once 12v power connected.
The NZXT H440 is a PITA ..... Phanteks Pro case makes the 5.25 bays optional. A Reven Six Eyes would be a perfect solution.
