Current, thermals and noise

Under full CPU load (Blender, five consecutive runs of the Classroom performance test), the highest number I saw was 461 watts at the wall. 435 watts was a typical draw under CPU load, with lighter workloads below 400 watts, overall. When the graphics card was doing most of the work, the power supply reached 501 watts at the wall.

In terms of thermals, I focused on the processor here, as it was cooled using a Lenovo solution and the NVIDIA graphics card used its own stock cooling. The Threadripper PRO 5995WX is a power-hungry part, and when all cores were stressed for a while (the same five consecutive Blender Classroom tests from the power draw test), average core temperatures reached 75.3C (~17C ambient ).

In terms of noise, under full CPU load the system stayed under 40 dBA, with the highest noise level observed at 39.3 dBA with the meter just 12 inches from the front panel. I was a little concerned when I saw that the CPU fans were only 80mm (and the case fans aren’t much bigger), but the system is well balanced and the fans don’t spin faster than necessary.
