I have most of it at about 40% on idle and gaming at about 60-75% if I remember correctly. I think you can lower the settings though (my cpu gets abnormally hot). This watercooling is also by far the best I have seen and used in a long time and should certainly be on pair with many 360mm radiators. I really don't think you can go wrong with this cooler tbh. (also the small fan is not loud don't worry ;))
