OctoMiner Chassis Fans all over the place

[rborgia]

Has anyone experienced any issues with the Octominer chassis fans? one case out of 11 cases randomly shows 10 fans, and randomly shows different fan speeds… I tried upgrading to the newest kernal and get the same issue.

Kernel: 5.15.0-hiveos #96

I did the Fan Controller Report in the octominer advanced settings, and get the following:

“USB error: error sending control message: Broken pipen”

I also tried recalibrating the fans… no change.

I thinking its a controller issue, but figured I would try here first.

Thanks!

Can you dm me a link to the worker?

Hi Keaton, I will need to set it back up, I pulled it off the rack last night to check all the connections. I can do this tonight when I am home from work.

Thanks!

Got it. Can you try swapping the fan controller between this one and another? That should rule out whether it’s a hardware issue or not

Sure, I will definitely try it, but will have to do it a little later tonight. Thanks for taking a look at it.

So, I swapped the controller board, same result. Randomly changing fan speed, showing random fan speeds on dashboard, showing 4 sometimes 12 fans on dashboard. I have the speed set to 30%.

It’s more likely a power supply issue. I had an issue with mine where it would intermittently display 12 fans when all I had was 4 fans installed. Out of the 4 PSU’s 1 was bad

You hit the nail on the head! Thank you for responding to my post. The first power dupply I swapped appears to be the issue. Gonna let it run and continue to monitor, but prior to the swap I would have 12 fans on boot up. Its also holding the fan speeds.
