So i installed a Cooler Master JETFLO 120 today in my case.
I plugged it into the motherboard and turned on the PC.
I noticed that it is kinda loud so i checked the speed of it and it was 1680-1690 RPM.
I wanted it to be silent so i tried lowering it but it didnt respond.
In the box i also got 2 adapters one was for silent mode(1200 RPM) and the other was Silent mode(1600 RPM)
I have havent put any of them just the one i got with it.
Now i am wondering how exactly do i get the 1200 RPM adapter on the fan and do i plug it into the motherboard again?

I am not sure if we are on the same level but the fan i bought was a case fan.
It is mounted on the back of my case.
