I was thinking about adding the hybrid cooler to my reference 980ti. 1, for better temps and 2, for a system that is more quite. 
 
so it got me thinking, how does adjusting the blowers fan speed effect the pump and rad fan?
 
for instance, after installing the hybrid cooler i would want to keep the blower at 20% (minimum) at all times (possibly let it go to 30%). but low enough to not hear at all.
 
would this mean less power is getting shared with the pump and rad fan (since their power splits from the blowers connection)? is the blower supposed to be set to a fixed speed to make sure the hybrid cooler is getting adequate power? for example 50% at all times?
 
 
 
 
sorry, i must have worded it badly. let me try again:
 
first, the facts: the hybrid cooler powers its pump and rad fan from the same port that the onboard blower fan gets its power from.
 
you put a header on the card that splits the power; 1 goes to the blower and another goes to the water pump (the water pump then powers the rads fan as well).
 
so i guess i am confused on how much power the pump and the rad fan requires to operate without any issues. it seems like a lot of required power. the single port that use to just power a single blower fan is now powering that same blower, as well as a pump and a 120mm fan.
 
i guess its not a big deal since this is how the hybird card was designed?
 
but my question.
 
you can control the blower fan speed from msi or evga software. but with the addition of the pump and rad fan, should you?
 
what happens when you set the blower to 30% speed? since now the pump and rad fan are sharing that same 30% power threshold? i just dont get how all that can be powered off a single header that is not running at full power. does the hybrid cooler require that the blower run at "at least XX% to function properly"?

Whatever you default fan speeds are with a reference card is what they will be after changing coolers.

Good thread for you.  I run the blower fan on a custom fan curve on AB.  22% up to 35C - 35% up to 45C and 40 up to 50C.  40 is at the point where I hear the blower fan.  It has never gone higher. Usually stays at 35%.  
 
I now run the pump and the aio fan off my fan controller.  

I run the AIO fan and pump on my 6 channel fan controller.  I do not know the rpm speed.  I do know that the fan controller controls the fan from 40 to 100%.  So I just have the pump running about 50-60%.  My pump did run pretty quietly before but now it is very very quiet. The resonating vibrations in my case is gone. 
 
I actually bought four of the adapter cables in case I wanted to sli. The biggest cost was shipping.  I paid around 17 bucks for 4 unsleeved. 
 
If you follow the instructions in the attached thread it is easy. I did not even taking the AIO out of the case.  Just removed card to side of case and set it on a shoe box and 10 minutes later I was done.
