I need a new quieter cpu cooler, my akasa one(AK-961) is driving me up the wall, and I wanted to know the sound differences between the Artic Cooling Freezer XTREME and Freezer 7 Pro. The artic cooling website gives the Freezer XTREME a sound score of 0.5 and the Freezer 7 Pro a score of 0.9. However there is no reference to what these scores equal in real life.
