So, 6 weeks later, the cable arrived, i opened up the card, removed all screws and removed back plate, connected the cable, ran it out of the 8 pin area, you have to connect it to a fan header which can be set as WATER PUMP, chaged the mode to DC, did a fan curve according to cpu temps, 40c - 60%
50c - 70%
60c - 80 %
70c - 95 %
 
My card is vertically mounted so you cant even see the cable , either way . I used some black isolation tape to wrap a bit of the wiring .
 
deffintely a difference in noise from FULL SPEED to 60 percent . unfortunately i dont have the option of controling it according to GPU temps, i tried using a 3rd party software called ARGUS MONITOR, but it messed up setting with my corsair commander pro which has 9 fan cruves for all case fans,
 
Heres a short clip on youtube , at first its on max speed . then reduced to 50-60 percent

    You can try to check if your motherboard has external thermal sensors pins and if it has - get one and place it near gpu behind backplate. That could be good reference to control pump and gpu radiator fans.

    i have thermal sensors from COMMANDER PRO, this is irrelevant, i can only control pump speed from bios, according to CPU or MB temps, so obviously its according to CPU, the whole point of this , is that the pump works at 60 percent on idle, i cant stand that hissing noise when my fans or at low rpm . 
     
    Btw, does anyone know if you can go lower than 60 percent ?

    I heard the pump might shut off if you go lower than 50-60% but not 100% sure.  These pumps aren't powerful as I would not recommend going that low as you could leave the loop running at a trickle effect of a flow.  Could see a rise in temps as well.

    My pump won't start at boot below 7v, though it will run and be very quiet at 6.5v, after being started at a higher voltage.  I was running the pump and rad fan off CPU temp but they were speed hunting all over the place and I was getting inconsistent gpu cooling because various games load cpu vs. gpu differently.
     
    Switched it over to kick up at 35C system temp in the MB bios, it runs 1000rpm fan and 7.32v pump at idle, then after about 2 minutes under any gaming load system temp will come up to about 35C or higher, fan speed jumps to 1800rpm and pump 10.5v.  This results in the GPU slowly coming up from 26C idle to about 50-55C, then sometimes dropping down a few degrees once the fans ramp up.  Works good for all games, very consistent temps and noise, no fan hunting.  Your setpoints may be different with this based on ambient temps, system sensor location and case airflow. 
     
    Obviously if you don't have system temp fan control you can't do it and since the system is not warm at boot you have to set a high enough minimum pump voltage to get it to come on.

    my bios doesnt allow me to set anything less than 60% on the DC MODE (which i presume is 7V), so ive made intervals such as :
     
    60% - 40c
    60 % 50c
    80% - 60c
    100% - 80c
     
    this way while in windows or doing anything but gaming, cpu will never be above 40-50c and pump noise will be quiet at 60%
    gaming is usually 60-75c tops. so thats fine for 80-100% pump speed and a bit of noise which is totally normal for full load gaming

    Why not control it from your commander pro? That way you can control from GPU temp. This is what I did. You can set it as a 3 pin fan (DC control) in icue.

    Will I have enough power ??
    I’m running 3 splitters off 3 connections already , that’s 9 fans off the commander pro.
    Does it have enough power to run 9 fans and the pump ?

    I'd be careful with that.  That's if you're referring to the commander as it has it's limits.  

    The maximum power per fan header (combined) is 1A per port (4.5A combined). Meanwhile, the maximum power for the RGB LED channels is 4.5A.

    so is it a NO GO ?
    commander pro has 4.5A limit .
     
    9 fans at 0.3 per fan is 2.7a.
    the aio pump of the gpu cant be using more than 1a, because that is what a mobo header outputs.
    so its a total of 3.7a
     
    would getting ANOTHER commander pro be ideal ?

    It's not ideal, especially for it's cost.  I honestly would either deal with the pump noise or perform the cable mod and run it off your MB and just have it set at a fixed setting.  There really is no point in running your pump on a curve or based on a erratic temp.  Doesn't do much in a performance sense.  Find a happy medium through benches and hours of gaming and you should be set with a one speed setting fits all approach that is tolerable in audibles.

    It is currently on mobo header , runs at 60 percent on temps under 50c , reaches 100 when gaming at 65c
    I need it to work on lowest percentage when pc is at idle , that’s the whole point of adding the mini gpu cable .

    Sounds good.  As long as you're happy with it, that's all that matters.
