Can anybody advise if it's hardware related?

Hi,

you gotta check:

admin sh env temperatures

admin sh env fan

also physical examination would be good - the air filters could got dust etc.

Cheers!

FAIL doesn't sound too good I must say, normally on a 12k with 4.x you should see FANs being rotating:

I am running 3.9.1 on it.
