Performance
With our focus being on a home server use of the Centurion 5 II most of our testing was limited to noise output from the hard drives and fans. Cooler Masters tool-less design for hard drive mounting is both easy to use and very quiet. At no point during testing did I even notice a hard drive spooling up or vibrating. Considering the amount of use we put it through this was impressive. The two fans did a great job keeping everything cool, even after we moved this box into a closet we had no overheating issues. I did notice the sound of the fans when they were running, but I wouldn’t call them loud. If I were to rate them between 1 and 10, 10 being a house fan and 1 being silent, I would give them a 5.
