My system

I haven't had any problems with my build but I want to change the fan speeds. I think that they are going way higher than they need to be and they are very loud. None of my temps ever go over 40 even while playing games.

I have tried going into bios and setting silent mode/customization putting different fan speed sets but when I say save and restart none of the speeds change, CPU fan speed stays at 2570~ RPM. i'm pretty sure that this is the only one that I hear as I think the chassis fans are fairly silent. I have also tried using the software that comes with my mobo called A-Tuning. Same deal, I change the "fan-tastic" fan speeds click apply but nothing changes. Am I missing something? I have also tried SpeedFan but i'm not really sure if that is even supposed to change it. Also CCC but I can't find a fan speed option anywhere in there.

Thanks for your help and sorry for the wall of text

are your fans 3 pin or 4 pin? if they are 3 pin they wont change speed unless you put them on a fan controller.

4 pin
ground
12v
Sense (rpm)
Control

If your have 3 pin connector your missing the control wire.

Bleh I guess so, sorry I really should have realized that. Guess i'll make sure to look into that for future fan upgrades. Thanks
