yours are weird do you think you can switch the back fan (the push fan) on both machines> I want to see if the problem follows the fans. If I recall some fans are different and the only fix is fan replacement.
I am also having the same issue. Same location and running off the same PSU (Dell 1000w server). One of the miners also has a temp reading issue though, not sure if that makes a difference. See pics
Already tried to upgrade to latest firmware. When I got them they were on stock firmware. Made no difference though.
