Well, I did mention that it is all liquid cooled. The rad and 3 120mm fans are up top. There are 3 more 120's drawing air out of the case toward the front, but other than that there isn't much high volume air movement. I just built this system and haven't gotten around to overclocking it yet, but plan to. So the idea was that since everything else has a fair amount of cooling (liquid) to it, I wanted to target the one thing that really doesn't have much option. There is no air cooled cpu unit, so the diversity of airflow in that area is limited. Hence changing the 40mm fan out to something a bit more substantial. It doesn't need to be 10x the air volume, just more than what is provide with the fan that comes with it. No worries, I'll just keep researching and see what pops up for 60mm with a high static pressure so that it's focused on that area. If you look at the board design, there are two heat sinks. One across the top of the cpu and one along the left side. So I'd like to cover a little more surface area than what is given. Right now there is no extra air flow other than the 40mm and that is directed at a very finite position.
Oh, I'm using the lian li 011 dynamic. So if you look at fan/rad placement you'll see that there is little airflow over that portion of the board when liquid cooling.
