Ouch, your options are limited. That is a nice case, but it is going to be hard to pull the heat off that Quad with the PSU right there. Sounds like your options are to switch the case, go to water, or back off your vcore a bit and see how high you can keep your OC. Any way to mod the case so that the PSU is up front? Maybe remove the lower hard drive cage and put the PSU there.
