Let me start out by saying that Im doing a build similiar to Jayz2cents Skunkworks. I know....WAY OVERKILL!!! Im very new to this and I apoligize if things dont make sense. Havnt decided on the majority of parts yet but know that I want to do custom water cooling like he did it. Going to have 2 custom water cooling loops one for the cpu and one for the dual 1080 video cards using the Caselabs sm8 case.

Going to have a total of 14 fans.

4 fans for the 560mm radiator cooling GPUs on bottom of case
2 fans for the 280mm radiator cooling GPUs on bottom of case

4 fans for 480mm radiator cooling CPU on top of case

3 air fans in front of case
1 air fan in back of case

I want to be able to control the fan speeds for the GPU rad fans separate from the CPU rad fans and separate from the air fans front and back. So 3 separate fan controls.

What is the best way to accomplish this so I can control the fan speeds to each of the 3 fan groups using BIOS or software program?

I was told you need to use the PWM 4-pin fan headers on the motherboard to control the speeds of the fans.

Jay uses 3 of these in his build to combine all the fans together

So im guessing you atttach all the fans you want to one of these blocks. Than do you buy an adapter that will have Molex on one end that attaches to the 8 way block and a 4 pin female connection on the other end that connects to the 4-pin male fan header on the motherboard? The adapters that I see only have 3-pin which than I think I would lose fan speed control.

What headers would I need on my motherboard? Three 4-pin PWM headers? And if I add in 2 of these pump/resovoir combos: https://www.ekwb.com/shop/ek-xres-100-revo-d5-pwm-incl-pump , will I need 2 more 4-pin headers for a grand total of 5 headers? The evga Z170 Classified motherboard as this: Fan Headers – 7 (2 PWM, 5 DC / PWM). Does that work?

Is there a better way to do this to accomplish what I want? Am I missing something?

thanks in advance for your feedback....im very new to this stuff

Your extremely crazy 5 fans are the maximum unless you have like quad titan x pascal and the Intel® Core™ i7-6950X Processor Extreme Edition (25M Cache, up to 3.50 GHz) playing Titanfall 2 in ultra high detail with a 4 8k ultra wide monitor and a 1600w power supply with 64gbRAM a case as big as a 5 cases combined and unless your overclocking all of this you do not need 14 FREAKING FANS
