Hi Brvzer, Thank you for your in depth analysis of my build. I really appreciate it. The number of rads can easily be offset by the speed of the Water pump which you can easily adjust and as you can see its an open case. The details of the Pump is listed above as well as the acrylic tubing size. I'll update the post with the other detail you mentioned and I'll prove that this system is more than capable for overclocking. Again Thank you!
