Everything fits pretty much perfectly and it's very cool (as in low temperature)! Not too sure if the thermal compound is properly applied (as I had some issues with the installation of D15) but I'm gonna wait it out and see how temps are when I'm overclocking.
The H440 is great. Easy installation, good possibilities for cable management, great airflow, quiet. Some nice extra features as well. Thinking of getting a few extra fans though (or just one, not sure). There's currently 3 fans in the front (intake) and 1 in the back (out). 2 CPU-fans, and 6 GPU-fans, 1 PSU fan. Works fine at the moment.
CPU is currently ~33°C @ idle at stock.
D15 is bloody huge.
Both 970s are 35°C idle at a 1523 boost clock, and the performance is simply amazing. Even Dead Rising 3 is playable!
One thing I'm rather curious about - when I disable SLI, the temperature goes up ~10 degrees. What's up with that?
