Hello,
I am new to building pcs. I had a fx6840 that I gutted the mb, hd,and the dd out of. My mb is a H57H-AM2 .My CPU was running extreamly hot, so I bought at Rocketfish Universal CPU Cooler. While removing my old CPU cooler I unscrewed this cooler from the mb. Now the rocketfish cooler has no adaptors that will fit in these slots, do I need a CPU retention bracket to be able to mount this new CPU cooler? If so does anyone have any ones in mind?

P.s if this is in the wrong thread I'm sorry!
