Acer Nitro 5 AN515-54 fan speeds not accurate

[ziiads]

my problem is when I set my profile for the fans everything seems to work normally but the problem is it doesn't follow the exact values set on the NBFC app for example if I set the fan's speed to 50% the current fan speed shows up always higher than what I set by 10% or so I'm trying to use the app because my problem is whenever I leave a game my fans stay on the same level as they were in-game even after a long time 30 or 40min after leaving the game until I restart the laptop or put it into sleep and wake it up again if there are some better fan settings for my acer nitro AN515-54 I would be more than happy to try them.

I included this pic as an example to see what's going on.
