Ryujin II Pump Speed Capped at 1770rpm

Level 7
Hi, my Ryujin II pump speed is capped at 1770rpm. I can lower the speed and it is reported correctly, but if I put the speed at max in armoury crate, the max it will go to is 1770rpm. Isn't the max supposed to be 2800rpm?

my id is the same
This is the unit that works properly ryujin II 360 noctua fans, the first one I bought:

USB\VID_0B05&PID_1988&REV_0200&MI_00
USB\VID_0B05&PID_1988&MI_00

AC firmware is 0104

When the replacement unit arrives I will inform you of the speed of its pump, if it goes to 1700 it would already be the 3rd defective AIO.

Another question, my asus rog strix z690-e gaming wifi board has a chipset temperature of 65º Celsius at idle and 83º while playing, is it too much? I think I'll put a fan oriented to the chitpset

I had high idle PCH temps (69-71C) after loading bios 2204. Here is what fixed them for me:
1. Go to bios page Advanced\Platform Misc Configuration.
2. Set PCI Express Native Power Managment to DISABLED. (Keep this disabled, or you'll have lots of WHEA errors.)
3. Set all the following to "AUTO": DMI Link ASPM Control, ASPM, L1 Substates, DMI ASPM, DMI Gen3 ASPM, PEG - ASPM.
4. Reboot into Windows.
5. Restart and enter BIOS again, go to same page.
6. Change all items in Step #3 to "DISABLED".
7. Reboot to Windows and check your PCH temperatures.

I have no explanation for why this helped. I had the options all DISABLED initially, and had high temps after upgrade to 2204. I set them to AUTO and the temps dropped. Then I set them back to DISABLED one at a time, trying to find which one made the difference. With all of the back to "DISABLED", I still had the lower temps (about 60C). It makes no sense, but it worked for me.

Thank you, I tried your recommendations, unfortunately the temperatures did not vary even daily, they increased slightly since inactive I saw 67º I imagine it will be due to the temperature of my room, I put a 140mm fan at 900rpm to make it silent, aiming at the chipset and I managed to lower it to 60- 62º idle, I can put it at 2000 rpm and the temperature drops to 56º but the sound is very loud, I think 60º is fine, I think that in my asus z790 hero I have about 55º idle, I imagine it will depend on the number of pci-e and m slots .2 in use, the problem in games I think it is due to the gpu itself since it completely covers the chipset and can transfer more heat to it, in this computer I have a 2080ti asus rog strix and it is quite large, I also tried a fan curve more aggressive gpu and something helps.
