We encountered a strange issue with our brand new HP Z4G4 computer.
It worked as it should for 3 days.
The 4th day we cold booted the workstation and the fans start blowing at a pretty hight rate. Higher then normal.
Normally if a workstation does this, the fan speed lowers when windows starts.
But it didnt.
The fans keep blowing pretty hard which causes severe noice complains.
We rebooted the computer 3 times but the problem was still there.
We turned the computer off (windows -> shutdown) but after new start the problem was still there.
I disconnected the power cable and reconnected it, then started the workstation and it was quiet again. The fans were running as it should.
Are there more persons who had this issue? Its a brand new computer so it worries me. I've seen more of this cases with HPZ420 workstations which had motherboard issues.....?
