Erratic fan

HP ProBook 430 G3
Microsoft Windows 10 (64-bit)

I've just purchased a nearly new ProBook 430 G3. Everything is working fine except the fan is behaving erratically. While idle the fan is off as expected, during intensive tasks the fan runs at full speed, again as expected. However while browsing the web, using Visual Studio etc the fan starts running but doesn't keep a constant speed. It constantly speeds up and slows down, its subtle  but noticeable.

 

I've used lots of laptops over the years and never seen this behaviour before. All the latest drivers have been installed along with the most recent BIOS.

 

Anyone know if all 430's do this or is mine faulty?

 

Thanks
