D-5 question
I'm wondering if I could run a D-5 pump off of the fan header on a GTX 1070 ?

Vario or PWM?

I'm considering two separate loops with a D-5 in each. Cpu loop will run off of the normal motherboard pwm header, for the gpu loop, I'm hoping I can run the pwm part from the gpu. Yeah overkill. what else is new.

are you talking about alphacools new VPP755 model?? keep an eye on them if you are. I had 1 of each version fail on me rather quickly. The rev 1 the impeller kept popping off the retaining clip. The rev 2 would sometimes not turn on with the system.
I wouldnt worry about trying to control the pump via pwm off the gpu, for one it will look like crap with a wire hanging off the gpu like that, secondly the temps you'll get just running water on a gpu will not change much if any at all by running the pump faster. For most we find a set and forget speed to be equally superior to having the pump ramp up and down. All you get is more pump noise without any difference in temps.

Then run one D5 off the cpu fan header, and run the other one off the "optional" cpu header.
You motherboard should have 2 of them.

Not advised due to current draw.
Most mobo's have a HiAmp header now for pumps specifically.
