I'm mainly working in virtual environments and often having to copy or move large virtual disks.
My z8g4 increases the speed of the front fan when the hard drives are under stress, but then it does not slow down anymore.
The same problem occurs with both Windows 10 PRO / for Workstation, and with Windows 2016/2019 Server.
For example, when copying a 200gb virtual disk, the front fan rises from 570 rpm to 1600 rpm in a few seconds and remains so until the computer turns off. If I restart the workstation the fans will return to normal speed.
From hp performance advisor the workstation sensors report always regular temperatures.
The hard drives used for virtual test environment are 2 ssd configured in raid 0
