I dunno .... as I said, when I am doing a water cooling build, I use the Formula so I have no direct experience installing air coolers on it. The main distinguishing feature between the Formula and Hero is that the Formula has a water block on the MoBo.
If you are not going to use the water block, why spend the extra money ? Now if you were going to use something like the Swiftech thingie.....the Formula makes sense again. Unlike the Corsair AIOs, the Swiftech is not a CLC (closed loop cooler), you can "open the loop" and connect the MoBo block to it with just two fittings and two sections of flex tube.

When doing a air cooling builds I stopped using the Hero because:
1. I can get basically the same board from a features and component quality perspective for $40 cheaper from MSI.
2. MSi (1.5 % 2011 / 2.24 % 2012) has a lower rate of returns than Asus (2.2% / 2.24%) does. It such a small difference I really don't consider it but a lot of peeps think Asus has a much lower returns rate .... was true 2010 and back but not no more.
3. Newegg has combos with the Intel CPus that drop another $30 off ya cost so my users save $70 when buying GD65 / 4790k (or 4690k) combos as compared to Hero / 4790k (or 4690k)
4. MSI doesn't have the BIOS bug that afflicts Z87 an Z97 boards .... check newegg reviews on the M7F and RoG Forum link I posted above for details.
