I've been trying all kinds of combination of bios and advanced power settings.
the bios can set the "idle speed" but the fan speed never changes.
the system will go into temperature throttling and no ramp up in speed. The fans should ramp up under load and higher temps.
Seems like I am missing something like a piece of software that hp specific for the z820 to work with the os.
I've scoured posts here and on google and came up empty-handed.
Any ideas?
