Hello everyone, this might be a stupid question since it's my first time building a pc, I just bought a Corsair AF120 quiet case fan with red led.
I plugged it in the pc and it worked and started spinning, the problem is that it's loud, my default case fan(the one that came in with it) was much more quiet.
I actually tried it in front of an expert and he said it's working fine, and when I went back home, I tried going to the UEFI asus bios utility because it was loud(to me) and I actually didn't find it,
the cpu's rpm went higher than usual, did I connect it to the wrong place? does it need a fan controller?

Your mobo has one CHA_FAN header. You may need to change a setting in BIOS Setup. See your manual, p 3.3, for the EZ Mode screen. At bottom center click on "Q-Fan Control". On that screen, select the CHA_FAN and near the upper right make sure it is set to DC mode, not PWM. Remember to SAVE and EXIT from Setup. This will set the header to use the proper type of control Mode for your 3-pin fan so its speed can be controlled by the mobo.

Now, your comment on the effect of fan location is intriguing. That really says a lot of the noise is being caused by vibration in one fan position. That may just be a result of the case construction, so you would have to place it in the "quiet spot". But maybe you can get little rubber washers to place...

Tell us a few more things so we can help.

1. What is the maker and exact model number of your motherboard?
2. Where is your CPU cooling system plugged in? I would presume at the CPU_FAN header of the mobo, but please confirm or correct.
3. Where is your case ventilation fan plugged in?

The Corsair AF120 LED Quiet Edition fan is of the 3-pin design. The only way to control its speed is for the mobo header to use Voltage Control Mode (aka DC Mode). Most mobo CHA_FAN headers on ASUS boards can be configured to do that, but often they are set another way by default and require an adjustment. And this is only do-able if you plug the fan into a mobo header, and NOT directly into a output from the PSU via an adapter. So the info I requested above will let us advise more precisely.

1- my mobo is an Asus ROG Strix B250G Gaming
2- that is correct
3- it is connected to the mobo header

I tried to change its place and it actually worked like a charm, the sound became much quieter
my case is a corsair 100R
my cpu is i5-7400
my gpu is 1050 ti
I currently have 2 fans, and one stock cpu cooler.
I don't know if that'll help know the problem but for some reason when the fan is plugged in the black area its loud(too loud) and on the red area its quiet.

But maybe you can get little rubber washers to place between the fan and the case top where the screws go through, to act a vibration dampeners and reduce that effect.
