[6.11.0] All server fans shutoff a few hours after startup.

This is rather strange, stock Unraid doesn't have any fan control, please try booting in safe mode to rule out any plugins.

I'll re-upgrade to 6.11 and reboot to safe mode now.

Well, it's made it all day without the fans stopping so you might be onto something. Here's a list of all of my plugins but nothing here looks like it would anything to do with fans. Any thoughts, anyone?

From the ones installed I would try uninstalling this one first, you can just rename the respective *.plg to for example *.bak on /boot/config/plugins to prevent the plugin installing after a reboot, if it's not this one not quite sure which one could be, I would remove a few at a time to try and drill down on the culprit.

I've been running in safe mode with zero plugins for the past week and thought I was in the clear, but it has happened again. Newest diagnostics attached.

 

I'm completely lost on what else to try other than this being hardware. I would appreciate any help from any of the devs.

Looks more like a hardware issue to me, you can try going back to the previous known good release and see if it still happens, if yes it's likely hardware related.

I can confirm the same happened to me. 

 

If memory serves, 6.11.5, 6.11.4, 6.11.2 all have the same issue.

I've also been experiencing a similar problem. After moving to 6.11 the cpu cooler/fan (bequiet) would stop running and the server overheat and crash. I thought it was the fan/cooler so I replaced the cooler/fan and case fans for all new artic AIO + new bequiet fans for the case.

The fans have stopped "stopping" all together, but what will happen is they'll work ok for a couple of days and then either freeze at very low rpms eventually overheating the server or freeze at high rpms (this bequiet fans go up to 3000rpm) getting quite noisy.

 

 

My server was still doing it, but I "solved" the issue by getting a couple of molex to 4 pin fan adapters and bypassing my motherboard fan headers completely. 

thank you, but this means running at 100%?

Stock Unraid doesn't have any fan control, see if the same happens after booting in safe mode.

Cross posting from:

 

I have noticed the same sort of issue on my end. Server has been running fine for years. However in the last month or so, after X amount of uptime days my CPU fan will stop spinning and the rest of the case fans will slow down to almost nothing. This causes the HDD temps to exceed the warning limit of 45 C. A reboot always restores functionality until another X days pass.

 

I have not made any hardware changes to the server for years, only upgrading Unraid versions as they release.

 

The timing does coincide with my Unraid upgrade from 6.10.3 to 6.11.2 which was done on November 6. (Issue also occurred on 6.11.5).

 

I will be trying to downgrade to Unraid 6.10.3 and monitor.

 

For reference, this is an Asus X470-F motherboard and Ryzen 3700x CPU.

 

I should add, I have never had any of the Dynamix plugins installed and the issue has happened 4-5 times in the last month or so.

Holy shit! I've been dealing with this for what feels like 2 months. at first I thought it was RAM. but I just watched the dam thing. all fans stopped its slowly overheated then killed itself from temp protection

Mine just started doing this 2 days ago.  Had no idea what happened until I was sitting in the room and all of a sudden it went quiet.  All the fans just stopped.  I watched as the temps rose until I decided to just reboot the system instead of letting it get too hot.

are we onto something here? had this with 2 different MB too, my solution for now is an Sata to 4x 4pin pwn adapter and running all fans directly from the powersupply (its all noctua fans and not that loud even on full tilt)

So looks like this issue is caused by a new Asus WMI sensor module and and a buggy Asus firmware on some boards, @OrneryTaurusfound this:

After 49 days uptime on Unraid 6.10.x (never was able to pass 10+ days on 6.11.x), I decided to give this workaround a try.

 

For Unraid you have to modify/add the file "/boot/config/modprobe.d/disable-asus-wmi.conf" instead of what is mentioned in the Reddit link. On boot it will copy it to "/etc/modprobe.d".

 

I confirmed that this worked because I no longer see the fan speeds in the Unraid dashboard, indicating that the Asus module is disabled.

My uptime is now 16 days using the fix that OrneryTaurus found and the issue has not reoccured.
