mATX cooling: Which option?

[Maqywhaq]

Hey guys, so I've been planning a new gaming rig for the last week or so and I've reached the point where every idea I'm having is triggering repeating loops of "but but but"

I kinda want to make sure I've got enough thermal headroom to overclock a 6700k, but the more digging I do, the more I want to revisit the idea of an AIO cooled GPU in the rig... But given the restraints of the air 240, I'm not too comfortable with the idea of actually slapping the H100i in there AND a Seahawk GPU... I've done some reading up, and people do seem to be able to get away with cooling an overclocked 6700k to the 4.6-4.7GHz range with the C7 and the NH-C14S. The thought is that I'd be much less likely to tax the CPU to max vs the extra headroom I may get using a seahawk...

With regards to case fans, I've left them out for simplicity, but I'm going to at least install a pair of static rated 120's as intakes and 80's for exhaust for air cooling. If AIO run, then probably any fans I can jam in there as intakes, with the rads running exhaust... But since I'm not that well versed, I'd prefer to have a few more thoughts to see if anyone can help shed some light on how I might want to proceed...

If anyone has any thoughts or an alternative suggestions, please feel free to share. I'm probably prioritizing quiet operation over sheer performance, but some noise while under heavy load isn't a massive issue, but that's kinda why my original idea was to go with an H100i and set the fans to run at lower RPM, whereas if I went with the H80i, its gonna have to work harder to keep the CPU cool...

Going H100 would give me a whole lot of headroom for the CPU, but I suspect my usage for the system will mostly be taxing the GPU... It's kinda why I've latched onto the AIO GPU idea...
