I have had an ongoing issue since I first got the Z840 end of July 2020 (before that had a few Z's 800/600).
I sit my PC on my window ledge, with the window open to keep it cool I have been doing this with all previous PCs since 2011.. it also allows my cat to come and go as she pleases.
The issue occurs when the PC gets too cold, the fans begin to ramp up.. even the memory fan ramps til 6000RPM*. It's ultra noisy.. the sensors do not show in speedfan (I'm guessing this is a security feature).
Any help would be appreciated.

HP makes the assumption that workstation(s) will be used indoors in the HP specified temperature range that they specify in the products specifications (look under the "Environmental Data" section
- Operating: 5°C to 35°C (40°F to 95°F)
- Non-operating: -40°C to 60°C (-40°F to 140°F)
if your lower temp range is lower than what HP specs, then you need to move the system to a location that meets the listed specs as the workstations ambient air sensor is not accurate when used in colder than listed temps
you can check the bios or use the HP supplied software to check the current ambient temp reading and if "0" then the sensor must be replaced by replacing the power button cable
