Yes most 3 wire fans are controllable when set to DC in BIOS and you have the option to adjust speed. There are some older 3 wire fans that are not controllable (like some LED bulbs are not dimmable). I would try the custom DC settings in BIOS.]]> Mon, 15 Jul 2019 07:41:49 +0000 https://forum.asrock.com/forum_posts.asp?TID=11876&PID=64784&title=asrock-h170m-pro4-dc-fan-control#64784 https://forum.asrock.com/forum_posts.asp?TID=11876&PID=64705&title=asrock-h170m-pro4-dc-fan-control#64705 Author: PanSamorost

Hello, is it possible to control 3pin fans on this motherboard via DC so that they don't have to run at full speed 24/7?]]> Sun, 14 Jul 2019 01:20:34 +0000 https://forum.asrock.com/forum_posts.asp?TID=11876&PID=64705&title=asrock-h170m-pro4-dc-fan-control#64705
