CPU Fan 2 and CHA Fan 3 Stuck at Max Speed

[Guy2346]

When I use any type of fan utility my CPU Fan 2 and CHA Fan 3 are stuck at max speed. Here are some screenshots:

They are creating a lot of noise and nothing I do to slow them down works.

EDIT: I have another fan that's connected to CHA Fan 1 that works perfectly.

Which fans do you have attached to CPU_Fan2 and CHA-Fan3?

If these are 3pin, withouth PWM, then it's not too surprising. You should still be able to have some control inside the BIOS though.

Which board do you have specifically?

ASrock b150 k4/hyper, I have 3 pin for all of them but only one fan lets me control speed. The bios fan setting don't do anything either.

EDIT: They apparently have "Smar Speed Control"
