MAG x870e Gaming WiFi - BIOS and MSI Center not reading CPU Temp or CPU Fans

[rabidding15b002e6]

I have a newly built rig with the aforementioned motherboard running with Win 11, 64gb ram, amd 7 9800x3d, nactua NH-u12a, msi 5070ti

When going into the BIOS the CPU core temp and CPU fans are not being detected - the fans will show some RPM status a bit but then turn off - It does see the case fans in other sysFan slots. The BIOS does detect everything else without issue.
The MB is up to date on latest firmware. I've reflashed, updated, powered off for hours, I have tried shifting the pwm and dc settings to no avail.

When using the AMD center, and also when using FanControl - both of these see the core temp, and the fans correctly - so the system sensors are working.
Though seemingly the bios keeps trying to take over control after each reboot. (I have the smart fan settings disabled on the BIOS - set at pwm 100% *I also tried at 50%). If I re-run the calibration with FanControl the fans then re-read and work again.

Trying to see if there is a full BIOS firmware fix, or setting to shift. Old threads for FanControl show this was an issue with these cards previously but seemingly patched out a while ago. Any advice would be appreciated.

Do you connect the fan via any chassis hub? and can you show a picture of how the CPU core temp is not being detected?

I'm kinda lost at the part where you say the BIOS is not detecting the fan and it still applies the fan curve at startup.

You have to set a temp curve, I have set 39°C for 4.20 V. That's the second from the bottom. Because the cpu will mostly run around 40°C in bios and when idle. Your fan wont kick in if left at default.
Smart fan mode is on at DC setting. I made a group with all 4 case fans I have so the one setting applies to all. My other 2 case fans have their own group also, there I have 40°C for 4.20 V.
If the curve settings are too high the fan will be greyed out and wont run.
Ofcourse this depends alot on ambient temps, if it's hotter then you might get away with higher temp settings or default. So you need to experiment with that.
Unfortunately the bios really has a grip on fan curves, overriding what you set in windows.
The 4 case fans are noctua with pwm etc. The other 2 are bequiet silent wings with only 2 wires, but still have their rpm reported. Because of the 2 wires they're probably more tolerant to what you set in bios.

UPDATE: Well MSI decided it was an RMA issue.

The main issue was the BIOS and the MSI center both weren't registering any CPU Core Temp, and the CPU fans weren't registering in the BIOS or MSI Center either. Maybe a random bad pin messing with the BIOS / MSI portion - was odd though that the other applications saw everything correctly. Hoping the next board doesn't have the same issue...
