    Posted: 29 Jan 2021 at 8:43pm
I just got my new pc today and everything looks good, but one thing that annoys me is the sound of the fan seems to be very loud, no strange sound though. I changed the settings in bios but didn't really improve anything. Looks like the chassis fans are not controlled by the bios and their speed is constant. Does anyone have any ideas?

Depends what fan and where it’s plugged in.   Most case fans are plugged into the motherboard and bios sometimes works.   Motherboards also have their own fan control software, like Asus AI suite, FanXpert, for ASUS boards.

If it’s a Corsair product like fans for the liquid cooler, you can use Corsair ICUE software,   It works pretty good.

It’s possible a single loud fan is bad, bad bearing. Or your pump for the Corsair cpu cooler is defective.

Lots of variables .

Good luck.

Thank you. In bios all chassis fans' speeds are NA so I guess they are not plugged into the motherboard. And since all fans are always at full speed maybe they are connected to the power supply. What can I do with that?

Yes, just checked the motherboard and chassis fans are not connected to it.

Yep, makes sense the  fans aren't connected to the mobo.   I would trace the wires from the fan/s and see where DS plugged them in.  I doubt directly to a lead from the psu. 

You can unplug the fans from wherever they go and go to the mobo Fan headers that are marked Cha-Fan #, 1,2, etc..  Then use Bios to control them.

If the fans are run to a seperate controller behind the back cover, like a Corsair controller or a header you need to use that controllers software, like ICUE, for example. 

Use your mobo manual to locate what you need.

Good luck.

On  more option...you can buy fan reduction resister cables that go between the fan plug and the psu, etc.  It has an inline resistor in the cable that drops the voltage to the fan, meaning the speed.  You  can't control the speed but they do work to quiet fans running noisy because of rpm.   I've gotten mine from Amazon.  Just match the plug.

Good luck

I traced the wires and they are connected to a board that controls RGB lights and fans. What's weird is I can control RGBs with the PCB but it does nothing to fans.
