Hello I have a question, I have a asrock b450m steel legend. im on bios 2.9 had a question. So ive never had a mobo do this. On cold boot the cpu fan and the cpu2, chfan2-3, start for a second and stop for 1 sec. Then the pc will show the post logo and the fans will immediately start at that time and boots as normal. Then if i restart it is normal as well this only happens on cold boot. chfan1 starts and stays on from when the power button is pressed through the whole boot. This problem only affects the above mentioned fans. Is this due to some mem checking or power check or somthing. As i said the pc is functioning normally other wise. Temps and fan control are working properly and ram is clocked right.
