Question Lacking temp sensor header - workarounds?

[anvoice]

I've got an Asrock Taichi x670e motherboard around which I'm completing a build with a custom cooling loop. Unfortunately I neglected to check beforehand whether the Taichi has a temperature sensor header - apparently it does not. So I'm wondering what my options are for getting water temperature information into the motherboard.

I noticed that the mobo has a UART header, so would it be possible to hook up a small arduino-like board to read the temperature and feed it to the mobo via UART to control fan curves/do emergency shutdown?

Is this even necessary, considering that the CPU/GPU will react to high water temps (say due to a broken pump) almost immediately anyway and throttle as needed?

I dont see any specific need to monitor fluid temperatures past "because I can".
You hardware will react accordingly to a failed cooling system, first by downclocking and then by shutting down.

Is getting water temperature to the motherboard mandatory?

For the sake of relevance, can you clarify where this UART header you speak of, is?

Looking at page 7, I think you're misinterpreting the ARGB header for an UART header.

No, just something I assumed is good practice. I know what they say about assumptions.

Bottom left of board, to the right of the audio header, says "UART1".

Edit: got a chance to look at the manual you linked, and indeed it's not labeled there. But it definitely exists, right next to the audio header. I can add photo if necessary.
