Fan Noise

[BearMCx98]

Hi everyone, I just bought a new pc (i'll put the specs in the photos) but the noise of the fans is really too loud when it does nothing and it's driving me crazy. I went to the BIOS and saw that some fans are like 60% even when the temperature is below 40 degrees. Considering I have 3 front fans, 1 rear, 1 top, a Noctua NH-U14S for the cpu and RTX fans, I guess the sum of all these fans makes the noise I hear. I tried to set the "silent" profile instead of the "standard" one but nothing changed (I'll put photos of what i've changed).
I thought I'd put "manual" but it's still not possible to decrease the minimum speed at which they operate. At the top I read "DC" and "PWM" but not knowing what they are I didn't touch them for fear of doing damage. I will be very grateful to anyone who wants to help me and remind them that I am a noob so please be understanding :)

Try changing fan speed with pwm. If it works, then the fan is pwm. If not, set it to dc.

You can't damage the fans with that. It's just about how the speed of the fans is controlled, with PWM being the modern method. Like @Jeppes there said, go ahead and simply try.

But try pwm first, you can damage Corsair maglev fans with lower than 12V.

Ok i tried setting everything to PWM and the graphics looked like the first photo i posted but the noise is the same. I've look at the rpm and temps in the BIOS and i'm preatty confused since it shows pump speed (that i think it's referred to water cooling, but i don't have one...) and not chassis fan 2 speed...

Furthermore it seems like the Chassis 1 is kinda high but i don't know if that's normal or not.

Btw i found under "Qfan tuning", "Chassis fan configuration" so maybe i can try to lower the minimum with that. Can you give me some advices on what rpm i can try considering i have 5 fans (plus the Cpu fan)? Thank you very much.

You need to lower speeds of Fan1, w_pump+ and aio pump. Pumps use same connectors as fans but those connectors marked for pumps can handle more current.

Hey, use msi Afterburner to set custom fan curve. Watch a tutorial video about it.

For cpu fan you can go pwm and manual. In the manual put the cpu fan to the lowest possible speed when its under 70c.

Chassis fans you can put to silent or do the same as you did with the cpu fan

What fans are they? Where are they actually connected? CPU and CPU_OPT header use same controller chip. Usually you connect CPU fans to these. If you have just U14S with single fan, you could put rear and top fans with splitter to CPU_OPT and have them be controlled with CPU temps. If they are PWM (4pins). I wouldn't use W_PUMP+ unless its the only other option. Looking that if you would use Y-splitter for rear and top, that leaves 4 free fan headers to be used. If all fans are PWM (4pins), you can just connect them and set headers to act as PWM. Or if you don't use splitter, its still 4+1+W_PUMP+.

 

BIOS/UEFI side can be bit confusing as you can't test how controls work in real situation. Since its Asus board, you can get their Fan Xpert software. Thats one of the better fan control software there is. It pretty much copies what you see in BIOS, but with the possibility to run stress testing or other heavy tasks while you tweak fan curves.
