Zbook 15 G6 became noisy after BIOS update.

HP Recommended
Zbook 15 G6
Microsoft Windows 10 (64-bit)


Almost new Zbook 15 G6.

Became noisy after BIOS update to 01.05.04  via HP Support Assistant.


Fans continuously work without load, even in idle. CPU\GPU are cold, about 40 C in idle.

OS reinstallation did not help.


Is there a way to downgrade BIOS, or other fix ?
