RickyTick Posted October 25, 2013 Share Posted October 25, 2013 The 200mm top exhaust fan in my 650D makes a terrible growling noise most of the time so I've decided to replace it. I can't decide if I should go with a pair of SP120's or a pair of AF120's. (or something else entirely) Any suggestions? Thanks in advance Link to comment Share on other sites More sharing options...
