I have used 2 Gaia and 4 EVO on systems and they are both very close, with the Hyper 212 EVO being maybe 1-2c cooler.
Do you think I should keep the Gaia or trade for the EVO? My 4670K at 4.2GHz hits around 75C on the AIDA64 stress test. Idle low 30C and load on games 50-60C. Would the EVO be better for overclocking? I know temps are practically identical with the 4670K on stock speeds.
I do love the screw mounting system on the Gaia, but then again I've never installed a EVO before; I heard it uses some scissor mounting system.
