I've got a 3120A in a workstation chassis and it runs on Windows fine. However when idling at temps of at 52-55C and drawing ~100W power, the fan seems to continually switch on for a few seconds then off again for a few seconds. The case has plenty of fans and sits under the desk in an air conditioned office @ 72F.
As the blower fan is quite whiney it's pretty annoying how it cycles in/out under no load but i can't find a way of tuning up the thresholds for active cooling as you can on GPUs. Or would disabling it (micctrl --shutdown) when not in use help?
