I got the notification just before Christmas for the Hybrid Cooler kit. Decided to go ahead and get it since I don't know when my OptimusPC Waterblock will be here and I can always give the hybrid kit to a friend who has the same card when it does arrive. Didn't really have room for the hybrid cooler radiator inside of the case so I had to improvise

Still running the 450w stock BIOS for now, but it maintains around 52-55C while gaming (~350-400w power draw) with a max of 50% (1500rpm) fan speeds on the radiator. I didn't put a 4th fan on the radiator since it would be completely blocked by the top part of the case. My case isn't really setup for air cooling, so the stock air cooler would routinely hit 75C while gaming with the fans running 2000rpms. The sound is much more bearable with the 240mm AIO.
