So, I tested the regulation from 0 to 100%. The speeds change, and I see how the fans work, but the information about the speed at which they spin is not displayed. It shows the screen above: Power 22% - just like for Socket 1 and 2, but instead of ~350 RPM, it shows 0.
These fans are connected to each other - there is no wire there.
But the fans are connected to the aquaero/motherboard with a cable - I also changed this cable.
To clarify what I did...
- changed the order in the "chain". Fan 1 became 2, 2 became 3, and 3 became 1 (to make it a cycle). Still RPM 0.
- connected the same fans with the same cable to the motherboard - RPM is displayed. Here the motherboard smoothly regulated in relation to the CPU temperature.
- changed the order in slots 1-4. The fans that were connected to socket 2 I switched to 3, and those on 3 to socket 2. And it turned out that socket 3 doesn't show speeds (RPM 0).
- even connected the fans to port 4. The same. 1 works, 2 works, 4 shows 0 rpm - but it controls the speeds correctly.
- checked the pins if they weren't bent...
Sometimes these RPMs rise to 100. But most of the time, it's 0.
As I wrote in the first post - just two days earlier, I was using 4 channels at once - each of them had 4 Noctua fans (NF-F12 PWM). And it worked well. All 4 channels showed speeds in aquasuite, aquaero, and in the AIDA system.
What changed besides the new fans:
Update of aquasuite, maybe from X.76-X.77 to X.78, and along with that, a firmware update (but I updated D5 NEXT and farbwerk nano, didn't update anything in aquaero).
What's wrong? The fans do not have any rgb... What is happening with the Aquaero controller?
Does HI require any updates? Are there any logs I can provide you with?
These are the fans:

I don't use the included device for fan control, to adjust the speed by pressing the appropriate button.
