Hello everyone, I am completly new to watercooling and would like some imput from u fellow OC members regarding this set up I have in mind. I just bought this http://www.frozencpu.com/ex-wat-19.html due to my opteron ideling around 40 c load 54c. With that in mind I said what the heck lemme just cool my video cards too... so Im thinking of getting this now too..http://www.frozencpu.com/ex-blc-185.html. Now my question is will I be ok in adding this to that water kit or will it just not work as good. All of this will be going into my current sig. Will water pressure drop? Will I have to upgrade to dual radiator? thanks.
