Hi i have a haf x case and i just want to change my stock cooler getting 79 celcius on prime 95 on my 3570K @ 4.2Ghz. I want to get a better cooler and i am convinced to get the 212 evo because i dont want to go any higher on my clocks... My question is will it fit using the back panel? i dont to take out the whole motherboard if i have to do that then i better not buy the cooler... Please i want a clear answer if i can fit the backplate using the opening on the back of the case
