STRIX B550-XP has high temps on AUXTIN0,3 and TMPIN4

[Atomicat]

Like it says, reading 85 to 95 on those three sensors.  All others reading in the mid 30's. Other than that, no problems.  Boosted to 4.5 Ghz, IceGiant keeps it in the low 80's on full load in a warm room.  Is this an anomaly?  Should I worry?

I updated the bios I saw that the first PCIe slot bifurcates to 8x4x4.  Does this mean it will handle 3 M.2 drives on the card in that slot?  Are there any other settings needed to be set to make this happen?  How do I configure for max storage?

Hello @Atomicat 

AUXTIN stands for Auxiliary Temperature Index, while TMPIN seems to represent TEMP PIN, which might refer to the temperature index of the CPU socket or other integrated hardware components.
Since we cannot confirm the source, frequency, or accuracy of the parameters detected by third-party software, we recommend monitoring temperatures using BIOS, Armoury Crate, or AI Suite 3.
And if everything is currently functioning normally, you can continue to monitor it during regular use.

Regarding the PCIe bandwidth, may I ask if your current model is the ROG STRIX B550-XE GAMING WIFI?
Could you please specify which PCIe slot you are referring to?
Please refer to the manual, particularly the "Connectors with shared bandwidth" section, for installation guidance.

If you have questions about the specifications, please share the BIOS image and hardware specifications to help us understand your desired setup.

Thank you.

After reading about 3'rd party (HWmonitor) progs, no longer concerned plus bios update seems to have fixed the issue.

It is indeed the XE version of the board with Ryzen 5950x processor.  I have a gen-4 M.2 drive in socket M.2_1, a gen-3 drive in socket M.2_2.  When I have my 3090 in slot 1 the adapter card is right up against the fans and has led to higher temperatures, have had to throttle the card.  I would like to if possible, have the adapter card with three Gen-3 M.2 drives in slot 1, and the 3090 in slot 2.  When bifurcation set to raid on slot 1, it will detect two drives.  When set to 8x4x4, only one.  I would have expected the 8x4x4 setting to be the proper one for three drives, as outlined in the faq.  Slightly unclear here, should I have those drives in the 1, 3 and 4 slots?

Hello @Atomicat 

We recommend referring to page 1-7 of the user manual for installation guidance on PCIe devices and referring to page 1-8 for the installation location of the Hyper M.2 and SSD configurations.

Thank you.
