yeah. I took my dads E8400 to 4GHz with that cooler with no problem. For the 45nm chips you really shouldn't go above 1.4V. At those voltages pretty much any cooler will do - except the stock one since they've gotten ridiculously small in the last gen. Quads are different since they produce way more heat, but duals aren't really temp limited.
once upon a midnight dreary, while i pron surfed, weak and weary, over many a strange and spurious site of ' hot xxx galore'. While i clicked my fav'rite bookmark, suddenly there came a warning, and my heart was filled with mourning, mourning for my dear amour, " 'Tis not possible!", i muttered, " give me back my free hardcore!"..... quoth the server, 404.
