It's ready to go out of the box, you don't need to add any coolant. Make sure your MB is mounted in the case before installing the unit and screw the fan to the radiator prior to mount it to case.
I am about to buy the Intel LGA2011 Liquid Cooling Thermal Solution (BXRTS2011LC)
I know how to install it as I just watched Intel's video on it, however, I could not get the part of the liquid insertion so here is my question:
Where do you pour in the liquid to the cooler? Should it go to the RAD that will be with the fan? Do I need to buy additional reservoir for the liquid?
From looking at the offer that I want to buy, it shows the pump and the rad and the Hoses...
Would you be able to help me out with this?
