I received the mounting brackets today and installed my Antec Kuhler 920 onto my GTX670, amazing results! 40c full load with furmark! 
with stock cooler: idle 35c, full load 78c
with Antec Kuhler 920: idle 24c, full load 40c
fan speed: idle 850rpm, full load 1800rpm
liquid temperature: idle: 30c, full load 37c
room temperature: 22c
Many thanks to Dwood for the brackets!
Here is some picture of my rig:
