thanks for answering.
The trouble starts with the intital 2-5 minute Bios setup which will go gradually through all fan speeds.
That test takes 1 second to go from 0% to 50% and then it takes 3 minutes to finish.
The results are the issue. It should find 3 fans that can be set from 0% upwards.
But it does not:
1 or 2 fans get detected correctly, but never all 3.
As you see on the left i am not allowed to set anything in the red area.
The right side shows a correct graph. But the precentage numbers don't match the associated rpm.
All other fans in the world run perfect with your boards.
And your DC-fan management for my Silverstone AP181 is the most granular of all board manufacturers. I test this since 2009.
I just have troubles with the new pwm variants: Silverstone AP184i pro and its predecessor AP183.
But the AP183 i could at least get to work after 10-20 setup attempts.
I will install as you requested and will come back to you.
