If the fan only has two wires, then they eventually use a trick to make a digital RPi pin analogue, because RPi only has digital pins. The trick is described here: Click!
I would still try to replace the fan. It's a cheap thing.
PS: It's also possible that they use a DAC to trigger the fan. Then also the DAC could be broken, but usually cheap fans are the issue.
I see. If I remember right, a fan needs 3 pins for variable fan speed, and 2 pins for single fan speed (on /off). So the theory is that the pin for speed control doesn't work. Consider to replace the fan.
Hmm don't know what I'm doing wrong then...install add-on from zip, change settings, restart...just get on or off, no variation in fan speed.
Check the GPIO pins.
The forum complained about a censored word (really?) so on arm_b00st replace 00 with oo
Sorry. I've sent a request to the admin to remove this word from blacklist.
Where’s the particular debug log setting and where will the file be?
I would love it use this as a daily driver but I have no access to the Kodi and librelec repository.is there and librelec 10 versions floating around or will I have to wait until Kodi 11 progresses
If you need official repos, try LE nightly: Click! To my knowledge, latest nightly builds also have HDR.
You can update by copying the img.gz file (use wget <YOUR_NIGHTLY_IMAGE_URL> on ssh) into /storage/.update, and reboot.
DOES anyone have a copy of the best HDR versions as all SMP Dropbox links are dead..Thanks heaps
This link works for me: Click!
GDPR-7 It's better not to ask for reasons here. We want to avoid any political discussion, because the forum is exclusively about technical support.
No problem, it's always a pleasure to help. 
Can you test the DAC on a different PC with the same USB cable?
I don't see the USB DAC in the log. If you have it connected to the USB hub, connected it directly to RPi instead.
symean Understand. Then I would connect the fan directly to the GPIO, so that it's always on.
A new Chromium browser is in the works. It needs an add-on sandbox, which takes a while. So don't expect bug fixes for old Chrome.
Edit your post, and translate into English please.
I have an Argon One case which has a useless fan, I've given up on controlling it's speed based on temps. I started a thread here but it got way too complicated for me. It feels hot on the top but perhaps I'm worrying about nothing, apparently it's still one of the better cases for cooling even with the fan off.
Read your thread. It has many new answers: Argon One Fan Control
Is there a simple solution to reenable USB DAC functionality?
Does the DAC appear as an output device on LE's audio settings? If yes, just select it, if not...
