an artic cooler freezer 7 pro should be good, but i doubt you'll reach 3.5.... maybe you might
its fine for duo's, i can reach 3.3ghz without breaking a sweat on my older e4500, it tops out @ 45C in a 20C ambient room
e4500 is harder to OC because its cap is low... the highest some people that can reach with it is 3.6ghz, and thats in overvolt territory
*edit*
e4500 is 65nm, the e7200[45nm] should actually run cooler... you probably will reach 3.5 with the artic cooler
