HP Zbook G5 x360 Fan Noise Problem

HP Zbook x360 G5
Microsoft Windows 10 (64-bit)

So I bought 2 Zbook g5 x360s and they both suffer from the exact same problem: Fan noise. 

When I turn on the computer, 50% of the time the fans start coming on at full blast for no reason at all. Also when the power supply is plugged in, you can definitely be sure that the fans will run at 4800 rpm even without any programs running. 

Its as if a plane is about to take off every time I plug the power supply in or just do some light web browsing.

 

I've browsed the forums and have already done the following 

1) performed a hard reset

2) updated bios to the latest version, and all drivers

3) cut down on all possible startup tasks, including HP's slew of horrendous bloatware that came pre-installed

4) adjusted the power settings in windows - aka limited the maximum processor state both on battery and plugged in to 95% and changed cooling to passive for both battery and plugged in. (Doesn't it defeat the purpose of of getting a workstation series if you are going to limit its full potential?? Limiting those thresholds didnt work for me anyway)

5) made sure the fans always on option is turned off in bios

6) opened the laptop to check if air vents are blocked. 

 

Unfortunately all to no avail, which is hugely disappointing considering the premium they are charging on this notebook. I've noticed that GPU temperatures constantly hover around 46 degrees and it seems that the fans just go full blast whenever they go above 50, which is almost always. I would really appreciate if someone could give a solution for this before I resort to sending both laptops in for servicing, if it even helps. (Really bad experience with HP customer support)

FYI, I've performed a clean reset and reinstall of windows on one laptop and still the problem persists. Perhaps it could be a hardware issue, but I'm starting to believe that its just the bad design of the product overall with heat dissipation issues. I mean both units, purchased one 3 months before the other, with the exact same problem, really?
