I've been using this CBO for six months. Server processor XEON E5-2680 V2 (10 cores, 2.8 MHz, TDP 115 W). Case Fractal Design 3000. CBO stood up perfectly, except that the radiator mount to the rear panel had to be "pulled" to match the screw holes. The rest is great. The fan speed at "idle" is 800 rpm, it is not audible. Under 100% load, it spins up to 1100-1200 rpm. The idle temperature is 23-25 degrees, under 100% load only the processor - no more than 65 degrees, together with the video card - 70-75. The pump, despite 2022 rpm, is also not audible. The general noise background is formed by practically only three case fans and the EVGA GTX1070 video card (in games). In general, the system is 5 points.
