" rel="nofollow - I have 3 pin fan that I connected to chassis fan 1.

It runs with maximum speed ~2900 rpm.

How can I set speed of this fan?

Dear Koikun,

Greetings, this is ASRock TSD.

When installing 3-Pin fan on the CHA_ FAN1, it only works at full speed.

If you would like to control fan speed, please install 4-pin fan on the CHA_ FAN1.

Please refer below link for the fan type specification and information.
