Those temps are very low. Use the software to slow the fans down. Yes, your temps will go up (some) but it's no big deal. When it comes to cooling, it's all about surface area, and the amount of air moving across it. Since that cooler doesn't have much surface area, it has to move a lot of air across it and hence the high and therefore noisy fan speeds. I would not recommend a slim 120 mm AIO for a processor over 100 watts, especially when noise is considered.
