Fan speeds on the laptop?

I noticed earlier that my laptop Omen an132ng, which has two fans, runs very different speeds. At the moment the laptop is more in "sleep mode" in the sense that there are no processes running on my part. Just the usual Windows processes.

Now I've looked at the speeds and one fan runs at approx. 2200 revolutions and the other at 220.

My question now, is that normal, this big difference? Or does the laptop get wrong values from one fan?

I also have an OMEN, but I can't find anything where the individual fans can be read. With my old MSI, only the fan was running, where there was a lot of load and thus heat. With purely CPU-heavy applications, logically only the one, with gaming the GPU came with. So should be normal behavior.

I see, I read the whole thing through speedfan. I took off the cover at the back and switched it on so I could see whether they were really running and the fan for the GPU actually only ran when the GPU was actively used. The only thing I was told via SpeedFan was that it would turn at 200 revolutions, at moments when it wasn't even running, I find that strange, the other one who supposedly spins at 2200 revolutions didn't look at all that it actually turned that fast, at first when the CPU was used correctly it ran at 3500 revolutions and also got louder, I think it is more likely. So iwie wrong values are displayed.

I just let the program run on me, it doesn't know any fans (probably from the OS or board). But as long as the cooling performance is right, I honestly wouldn't worry…
