I have AB350m pro4 and it has two 4-pin connectors and one 3-pin connector. I have 3 4-pin fans connected to CPU connectors and one 3-pin fan connected to 3-pin connector. I control all of them via Fantastic tuner in Asrock utility. The point is if you connect 3-pin fan to 4-pin connector it will work at MAX speed so use 3-pin connector instead if your MB has it. In fact asrock fan control in bios sucks because it is very limited. For example MSI boards allow you to chose either you want to control your fans with PWM or voltage on any connector.

upd. just checked photo of your MB and it does have a 3-pin connector, just use splitter if you want to connect 2 fans into one connector. As far as I know it can hold 1A so it should be safe to use several fans on it if they don't exceed 1A total

you can get inline resistors

noctua do a cable that has a resistor in it to reduce the fan speed and noise

or a seperate controller for example my case has one integrated with low high and off

Hello Everybody!

I have two fan in my case with 3 pin. I would like to make them slower, because they are on full speed with big noise. How could i control it? Is there any kind of program or options in bios?
