Pro Display XDR

Hey guys,

For some reason 1 of my 2 Pro Display XDR's fans are stuck at full blast, and no matter what I do it doesn't seem to change it. Any ideas, or should this one be exchanged?

Exchange it.

You can try and compare the DisplayDiagnose command between the two displays to see if something stands out.
/System/Library/Extensions/AppleGraphicsControl.kext/Contents/MacOS/DisplayDiagnose -a > DisplayDiagnose.txt 2>&1

Thanks @joevt - exchange it is. Didn't see anything from my eyes that I could see was different between the two in the diagnostics (most of it didn't mean much to me anyhow! haha)

I thought maybe there could be a temperature difference in some of the sensors (each LED has it's own temperature?) to explain why the fan is always on.
It would have been interesting if it could detect a problem, but there's probably nothing you could do about it.
