Need some advice with my setup.

Hello everyone
Im gonna make my first watercooling rig during this Christmas, then I need some advice from more experienced users.
My setup is 6850K, Asus Rampage 10Mobo and 1080TI.

1. I'm gonna use clear fluid( not big fan of dyes or stuff like that)to bleed this build then which one is the best?
What should I add to this fluid?
2. I got Alphacool VPP655-PWM pump, and pump got 2 connectors one is typical molex, and another one 4 pwm cable but there's only 2 pins on it.

Should I connect this 2 pin PWM cable to motherboard and molex to my power supply?
I read somewhere its not good to connect any cables to mainboard, but this pump doesnt have any flow regulation and pump can only be regulated from bios then I'm pretty confused where to connect power when I'm gonna bleed this build.

I was thinking to connect molex through extension to sata power connectors, and bleed all radiators, waterblocks and after when it's done reconnect pump to mainboard to eventually setup speed of the pump, but I dont know if my thinking is correct or not.

Any help would be greatly appreciated
Many thanks

From what I could find is that your pump just connected with a molex and no 4 pin plug will run at a default 60%. If you connect the 4 pin plug to your CPU header and then change your fan curve to the maximum, it will then run at 100% for bleeding, once your happy it’s bled then you can reduce back down to where you need it.

Thanks mate
I appreciate a lot.
I think I know how to connect the pump, but what about this question?

If you are buying ready to use watercooling fluid, you don't have to add anything, easy. You only have to add if you're using distilled water as fluid.
