I know, it seems a little silly at first, but I'm still a little concerned. I recently installed a CM Hyper 212 Evo for my Asus P8Z77-V motherboard in my CM HAF 912 to cool my 2500k so I could overclock it. After installing it, I found that I could rotate the entire heatsink a little. It's still fine for cooling at stock, but I'm worried about overclocking. Did I install it wrong? Or should it be like that? Also, if you can, can anyone reccomend good clock speeds for 2500K on the 212 evo? Thanks.
