PWM values occasionally get reset to 0

electricboy6 commented 3 weeks ago

Describe the bug On my computer, the PWM values for my fans and AIO pump occasionally don't set or reset to zero. This is usually a nonissue, but my computer just hard reset due to thermal throttling. The CPU usually never goes above ~75C, so it is not a cooling issue. The logs indicate that all of the fans just stopped ("PWM mode stuck to 0"), then I have nothing more as my computer hard shut down.

Expected behavior The fans do not randomly stop/change speed

Additional context I have been having errors like this for a long time, but it never actually caused an issue with my fans. This was the first time that something bad actually happened due to errors like this.

Hi @electricboy6 thx for reporting :heart:

Without a way to reproduce your issue it will be difficult to find a solution. How sure are you that this is caused by fan2go and not by the hardware driver? Changing the fan mode is done by simply writing a number to a file, if that fails the linux system is preventing fan2go from changing the mode (and also anyone else). Knowing the reason why it is preventing this change would be necessary. Maybe fan2go breaks the driver somehow, maybe the driver has a bug, or maybe its something else entirely.

Unfortunately, I have no way of knowing what it is caused by. At the very least, I hoped that posting an issue here would allow me to get some suggestions on help for it. If it helps at all, I'm running an Asus X570 board (I know the other info, but I doubt it would be more useful) with a 5900x. I gained the ability to control my fans when I updated to the 6.2 kernel series in case that helps at all. I didn't include a way to reproduce because it may be specific to my hardware as I don't see other people reporting this kind of issue.

It seems that it is likely that it may be the driver, but I have no way of knowing how unless you have an idea on how to catch it. It happens often enough that it would be trivial to find an occurrence to troubleshoot further if you know how. Sorry for wasting your time if it isn't fan2go, but it would be nice to know at the very least why it is happening or how to fix it. I would be willing to run a script that would log more detail about the error if you know what said script would need to do.
