Noise Level Results
With the sort of performance we saw in the NiC C5, the basic rules still apply. If you have a smaller design, it only makes sense that the fans used to gain that level efficiency will typically be louder than all the quiet offerings we have seen lately.
That being said, when I am going for a new personal overclocking record, I don't care how loud it gets. The 37 dB rating is noticeable, but again this can be adjusted to suit your needs.
When I had the VR controller spun all the way to the right, the fans really come to live and deliver a ton of airflow and no doubt a serious amount of static pressure. There is no denying these fans will overtake a room with noise with the 69 dB rating, but you have to do these things to get every last drop out of a single tower cooler design.
