They are both good rads yet I still like Thermochill myself. I currently have both in a system right now though the GTX is only a 240 for my Ultra card on EK block. My PA120.3 with three Silverstone FM121 fans in pull at half speed 1200RPM or about 55CFM is holding my slacr quad running 4G at 1.65v bios with idle temps of 22-23-24-27C and sustained temps of 38-38-39-42 with the room at 58F. Measurements taken just ten minutes ago.
