When the H100 has been compared to the big three heatsinks, it does cool slightly better, but much more loudly. There ain't no free in cooling. Water coolers just transfer the heat to a place that's more convenient to exhaust it, but a 120mm aperture is a 120mm aperture. And the final fluid to which the heat is transferred is the air. You can squeeze it through a rad or blow it gently past a heatsink. Guess which is quieter?
A 2x120mm rad will be quieter. And a 3x120mm rad quieter still: twice and triple the apertures of a 120mm rad. No magic involved: the cpu generates heat and it has to go somewhere, get transferred to something.
Any case that has a position for a 120mm exhaust fan has room for a full tower cooler like the big three: Phanteks, Silver Arrow, NH-D14. You need a case that can handle a 140mm exhaust fan to handle an Archon reliably, though some cases have the room despite having only a 120mm exhaust.
Best: buy a nibbler, cut out your rear grill, let your heatsink blow the heated air out the back. Quietly.
