Nitro 5 fan won't get back to initial state / lower speed ?

Rio99

After doing some tweaking to my laptop, now i'm really happy with my laptop, Nitro 5 i7 9750h with GTX 1660ti.
For inital state from turning on my laptop or resume from sleep, my CPU and GPU temp is steady around 39-45 degrees C with fan speed around 1900 - 2300rpm.
If just using my laptop for browsing or doing some work, it won't go over than 50 degrees and also the fan speed keep at such level, which is quite, awesome...

But there's something i want to ask about, i don't know how it works or it's normal or not.
Say, i use my laptop for gaming, my CPU and GPU load will go over 40-80% , and they reach around 70-75 degrees C, now the fan speed will auto adjust the speed to 4000-5900rpm, it's very loud now which is i think normal under this situation.
But... when i already stop playing and got nothing to do again, i check that my CPU and GPU temp. go back to 45 degrees C, very good... but, the fan speed still at 3000-4000rpm, which produces medium noisy sound, and even when i try to keep waiting for next 10-15minutes, it still won't go lower than 3000-4000rpm .. 

So, what going on here? Can you please help me?

From my point, since the laptop is not doing any work and the temperature for CPU and GPU are stable at 40-45 degrees C, the fan speed should also goes down to 1900-2300rpm. 

Thanks

Do you have fans set on auto in Nitrosense? If you do try this. Before you game put the fans on Max, I always game on Max, when your done gaming and temp has dropped back down put them back on Auto and they should drop back down to the slower speed

Yes, i put the setting to auto , and even try to put it on custom with auto.

Based on your condition, so you set the fan speed by manual and after finish playing, you set it to auto again?

Yes I set mine on manual at maximum while playing games and then when finished and the CPU has cooled down to normal I put it back on auto

Yes, i also use this method, but not set it as maximum for playing games just like you. I just leave it as auto... and after i finished playing and the CPU has cooled down, what i do is i just click CoolBoost button. 

I try your method, it also work. Thanks.

But i think it's just a little workaround, not a full solution from NitroSense that i thought will decide itself on what RPM the fan speed run.
