I have an Z820 with dual Xeon E5-2687W CPUs, liquid cooling. BIOS updated to v3.94
When I run high CPU load work, the CPU temperature reaches 80-90 Celces degrees. I tried to tune the fan idle speed in the BIOS, and it help to control the temperature when the idle fan speed is set high. However, I don't always run high load work on this machine and it is really noisy when the idle speed reaches level 4.
Shouldn't the cpu fan speed be automatically adjusted according to the cpu temperature and cpu load? I would expect this to be a standard feature for this expensive workstation. I think I am running the newest drivers downloaded from the hp support website. However, the HP performance advisor app just crashes the system every time I run it. It disappears after the system restart. So I couldn't verify if everything is up to date.
Please help me solve this issue. It might be a common problem as I saw many people with Z420, Z620 also have similar issue.
My guess is a driver issue or compatability issue with windows 10 system.
I appreciate any help!
