How can I power 10 case fans (and CPU cooler) inside my case?

I am looking to power 10 case fans in my build. Here are the relevant specs:

Case: Phanteks Enthoo Primo PH-ES813P_SRD Black/Red
Case Fans: 10x Phanteks PH-F140SP_BK_RLED 140mm Red LED Case Fan
Motherboard: ASRock Z97 Anniversary LGA 1150 Intel
Power Supply: CORSAIR TX Series CMPSU-750TX 750W ATX12V v2.3 80 PLUS BRONZE
CPU Cooler: Cooler Master Hyper 212 EVO

The Phanteks Enthoo Primo has a PWM fan hub that supports up to 10 fans being plugged into it. Ideally, I'd like to use ONLY 2 fan headers on my motherboard: a 4 pin fan header for my CPU cooler and a 4 pin fan header for the fan hub. I would plug all 10 of my case fans into the fan hub and then plug the fan hub into a 4 pin fan header.

The issue is that each of the 10 fans has a power draw of 0.14A, meaning that 10 of the fans would have a power draw of 1.40A. I'm aware that the typical fan header can only support 1.00A.

So, I really don't know what to do in regards to powering all 10 fans. Does the fan hub in the case have a resistor that limits the power draw? If not, how should I power all 10 fans? Should some be plugged in directly to the PSU? How many? How many into the fan hub? How many into the other free fan headers on the motherboard? Also, someone told me about a molex connector that might help with this situation but I'm not familiar with that at all.

I know this situation is a little strange, as most people don't want 10 fans in their case. I haven't decided 100% that I'm going to be using all 10 fans, but I'd like the option. So, can anyone please help me with this situation?

Thanks so much!

  1. Get a MOLEX to 4pin adapter ortwo, or a molex to 4pin hub if you can find one. Hook it up directly to your PSU and there you go.

    Here is a cheap onehttp://www.amazon.com/Phobya-Y-Cable-4-Pin-Molex-Sleeved/dp/B005EGL4S2/ref=sr_1_3?s=electronics&ie=UTF8&qid=1451864591&sr=1-3&keywords=molex+to+4pin+fan

    So how exactly would this work? Would I plug all the fans into the fan hub and then there will be a PWM cord going to one of the mobo fan headers and also this molex adaptor coming from the fan hub and going into the PSU?
  3. Dont let the cat or small children walk near this computer . They could be sucked into the air inlet
  4. Best answer
    Basically 1 fan connector of your mobo will control all other fans connected to the hub but the power needed will be drained of the separate connector directly of the psu.

    So the cord going to the motherboard will just be for the PWM signal and the molex connector going from the fan hub to the PSU will be responsible for powering the 10 fans?
  6. Exactly. Also 1 of the hub ports will read and send rpm signal back to the mobo.
    Try keeping same specs fans on the hub to avoid big differences in rpm's

    Ok, so let me get this straight. There will be 9 things plugged directly into the fan hub:

    1) Molex connector going from fan hub to PSU
    2) PWM signal going from fan hub to mobo
    3) RPM signal going from fan hub to mobo
    4) a single fan plugged into the first fan slot on the fan hub
    5) a splitter plugged into the second fan slot on the fan hub so 2 fans can plug into the slot (but only 1 fan will be plugged in because I'm using 10 fans not 11)
    6) a splitter plugged into the third fan slot on the fan hub so 2 fans can plug into the slot
    7) a splitter plugged into the fourth fan slot on the fan hub so 2 fans can plug into the slot
    8) a splitter plugged into the fifth fan slot on the fan hub so 2 fans can plug into the slot
    9) a splitter plugged into the sixth fan slot on the fan hub so 2 fans can plug into the slot

    The fan hub only has 6 fan connectors and each of the fan connectors except the first one can have a splitter for 2 fans plugged into it.

    Am I understanding this properly or are 2) and 3) the same cord?
  8. Yes, 2 and 3 are 1 cable. Also get a hub or 2 if needed instead of million Y-spliters haha
  9. You want something like this

  10. Thanks so much for your help mp5mafia!!
  11. No problem man
  12. Plug 8 fans into the header, and 2 into the 4pin hub.
