The 2U chassis has 2x fans, the 1U has 7 as per the manual.
Now how do I monitor temperature to make sure the thing doesn't fry?
This script does not appear to work for the 2U Mt Jade platform with firmware 2.10d... any chance for a fix?
Hi thanks for the question. There’s no fix because this script is only for its original server.
I got it from Ampere who now have an active developer forum. I’d suggest you ask there

@ppouliot I have figured it out!
Needs to be
2..7- the 7th fan is the one that was being left out and which was causing all the noise.
