I have a low strange sound in the background all the time. More frequent the more the computer is working. It sounds like the access of an old hard disk, but is lower. It is not the basic fan (I know how that sounds). My guess is that it is another, small, fan used for a specific part of the computer. The problem is that the sound is intermittent (not constant) and it is very annoying. HP Help Desk says "turn in the computer for a week and we will have a look at it", not an option at the moment.
If there is a small fan causing this "noise", is there a software fix for it? Or can it be something else?
Grateful for any help,

I solved this issue, but the cause of the sound is really far-fetched....
Anyhows, I found out that the sound was connected to the scrolling feature (documents, web sites). Separate mouse or built-in, didn´t matter, both caused the annoying scratch sound. Then in another forum someone suggested that it was the external PS that caused the problem. So, I unplugged the computer, and off went the sound!
Not the first thing that comes to mind.....
To anyone that has this problem: Unplug the power supply. If that helps, get another PS - (and make HP pay for it).

Sounds like GPU fan Staffan55. You should really clean your computer from the dust bunnies...
As for software fix look at this:

Thenk you for your answer. But the computer is almost brand new and I don´t think much dust has been gathered yet. I also had a problem with the "Intelligent Charging Scheduler", causing the main fan to go hay-wire, but that was solved. This is yet another problem. But I´ll have a look at your suggested software.
It is however not very reassuring byuing an expensive computer and experiencing several problems. My cheaper HP´s never had anything like this.
Anyway, I´ll try the tips I get and hope they will work.

You should run it with the bottom cover off and flip it over so as to see where the sound is actually coming from. Perhaps you need a new fan. ZBooks are powerful machines and they have thermal issues.... Cleaning it out never hurts, sometimes some dust gets caught on a fan and it becomes noisy.

Thenks again, I will do that. But how many fans does the computer have? This is not the main fan though. And again, digging into the bits and pieces of a brand new expensive computer does not feel good. What has HP to say? Is this due to a bad H/W design?

Cleaning the laptop with compressed air after taking the back panel off is routine user maintenance. Like cleaning your car.
Your laptop has two fans as seen in my previous post's picture. One cools your processor and the other for your graphics video adapter.

They're designed to only rotate when needed. If you want constant behaviour:
Check/Enable BIOS F10 option: Fan Always on While on AC Power (unchecked/disabled by default):
F10 Settings\Advanced Tab\Built In Devices Menu\Fan Always on While on AC Power

Now it´s a bit spooky. I have opened the service hatch. The computer is perfectly clean inside, no dust, just to be sure I used some air to blow the few particles away. The sound still remains, and when it sounds, the fans both are still. They´re not moving at all. So it has to be something else. It might not be a device with moving parts, it may be the sound system. I will have a look into the BIOS to see if there are any setting I might try there.
But at the moment I´m clueless. A real detective story 🙂
