I would definately get a Tuniq Tower 120, Thermalright Ultra 120 eXtreme, or Enzotech Ultra-X over an Arctic Freezer. Your temps will be at least 5C lower, I would not be suprised if you run 9 or 10C cooler at load compared to a Freezer 7. Check out Knitelite and Audi's thread comparing an Ultra 120 to an Ultra-X; at stock they idle at 19-20C.
