Most HP laptops have a fan always on setting in the BIOS/UEFI. It's enabled by default by design and isn't dangerous. Having it always on helps keep the laptop extra cool when the CPU is idle.
You may be able to turn this setting off if you find it annoying by restarting Windows then repeatedly press ESC as soon as the screen goes black until the Startup Menu appears. Press F10 for BIOS setup. You should find the Fan Always On setting which is usually found under System Configuration.
The Fan in a good laptop can run forever at lowest speed (I think your speed above is low speed).
All my laptops going back some years have CPUs that pick their speed according to load and the Fan works with that.
No danger in having the Fan run continuously on low and speed up when needed.
Note: Laptop manufacturers design the cooling system in their machines. So you have to live with what the manufacturer offers. Do not try to turn the fan off because the CPU could quickly overheat.
I should note that I serviced a ThinkPad with a Fan error. The machine would start, the Fan stopped and the machine shut down instantly.
No needed to worry about your fan running all the time and indeed, take comfort in it.
My system is the i7/gtx2060 model. Since the fan could always be heard, I decided to try this option out in the BIOS. It works great. Fans turn completely off until my CPU gets to around 55-60 degrees when they turn on again, cooling it back to 45-50 before turning off again and so on.
My question is though, would this be doing any harm?
Depending on what I'm doing, it could do this process every 5 minutes or so. If I'm just browsing, it would turn on less frequently. It stays on for less than a minute before turning off again.
Is there a way to have it turn off only when I'm on battery?
I've already undervolted my system and limited turbo boost (unless I'm gaming).
Appreciate your inputs!
