Trelor
Well I have installed my Hybrid and I have had it running for 2 Days at 2126Core and 10,800Memory. I love this card, it has replaced my since sold GTX 780 SLI setup. I am running at ~49C now with Dual ML120 Fans in a Push Pull on a fan controller. The best part is my office is not 90degrees anymore. and my power usage went from 795Watts gaming to 420Watts. The wait is worth it, however I do think I am going to be buying another Hybrid, I just miss SLI, still need to decide on a case though.
I think this is the best fan configuration if you have the room and are overclocking.
As a test I purchased another fan for my Sea Hawk to run it in push/pull and I saw a 5 to 6 degree Celsius drop by just adding a fan. No fan controller though. I'm using the motherboard bios to control the fans.
The fans I'm using are the Cougar CFD120. The combination of low noise, high cfm and decent air pressure are the reason I use them. These fans are rated at 1200 rpm but I've seen as high as 1350 rpm in my setup. I have them setup to stay very quiet at idle(50% @ 30C) but they ramp up as temperature increases while still remaining pretty quiet. It's been working really well so far.
