Similar issue with different mainboard (X370 Pro4); updated to the latest version (7.10) and now chassis fans spin at 100%.
I managed to control the fans with SpeedFan, but until Windows is
booted up, it's extremely noisy.]]> Fri, 04 Feb 2022 16:55:29 +0000 https://forum.asrock.com/forum_posts.asp?TID=21108&PID=92910&title=b450m-steel-legend-fans-broken-with-latest-biospound#92910 https://forum.asrock.com/forum_posts.asp?TID=21108&PID=92725&title=b450m-steel-legend-fans-broken-with-latest-biospound#92725 Author: Mistral

Minor update: installing ASRock's "A-Tuning" enables the correct rpm in Windows. That's an OK workaround, but it would be better if things worked right out of bios like before.

EDIT: I take the above back, partially. Even with A-Tuning installed, the fan profile only works correctly some of the time... Is nobody else experiencing this issue?]]> Tue, 18 Jan 2022 10:04:27 +0000 https://forum.asrock.com/forum_posts.asp?TID=21108&PID=92725&title=b450m-steel-legend-fans-broken-with-latest-biospound#92725 https://forum.asrock.com/forum_posts.asp?TID=21108&PID=92677&title=b450m-steel-legend-fans-broken-with-latest-biospound#92677 Author: Mistral

My B450M SL came with P3.30 and I had set a custom fan PWM profile for the chassis fans that started with 3% at 50 degrees (as with my fans that results in 400 rpm) and so on and everything worked beautifully.

Yesterday, I decided I might as well update to P4.20 - update went well, then I did the load bios defaults and an extra restart, then went back into bios to set everything again the way I liked it.

Thing is, upon restart, my chassis fans run max speed, as if the profile was not saved. If I go back in bios, the setting are there, and the moment I start editing them I can hear they kick in and run the fans at the intended speeds. All is good, until I shut down or restart the PC, when fans run full-blast again.

Any solution to this? Anyone else experienced that problem with the latest bios?]]> Sun, 16 Jan 2022 01:23:57 +0000 https://forum.asrock.com/forum_posts.asp?TID=21108&PID=92677&title=b450m-steel-legend-fans-broken-with-latest-biospound#92677
