I wouldn't bother with the H55. As others have said, you'll get better performance from a 212 Evo, Noctua, Cryorig. Had a 212 Evo myself, they're brilliant. Upgraded to a H75 as I damaged the fins when I was cleaning my PC and wanted to try it out. I get around a good 10-12c lower than I did before, I love it. But for the price, you can't beat the 212 or the other air coolers mentioned
