No, I tried it last year when I bought my Argon One case. I think it was with a Home Assistant Operating System 5.0 beta.
@KCYeoh No I havent, the case still has to arrive 
wondering if there is a custom component available for regulating the official Raspberry fan too? https://www.raspberrypi.org/products/raspberry-pi-4-case-fan/
Update:
custom component not even necessary: Raspberry Pi CPU Fan Automation - #36 by DarrenHill
Hi, just want to post an update here. The Misiu/argon40 is still working with the latest Core and OS. I installed them through HACS.
You still need to enable the I2C, but it is just one time deal.
ok thanks. It’s just that it isnt in the manual there… Or did I overlook it reading it the 10th times I checked.
btw, Argon has arrived just now!
dont want to talk about @misiu s add-on too much here, but cant find a dedicated thread? Anyone got a topic thread for that?
I forgot that part 
The easiest way is SSH the pi and run raspi-config 
Thanks
since I got my Argon case today, there’s been no way I get the fan to run… its way too cool
did try to set the config to a lower threshold, and was a bit surprised by the noise the fan made at only 1%… guess its a good thing I have it in the attic after all…
can someone help me figure out how to make the argon one reboot after power failure. i dont need all the other active cooling stuff as it sits in a server room.
I think you only have to set the jumper on the Argon One board to the correct position (I don’t have it here, so I can not write it). It is written in the Argon One documentation.
Yep. Page 6. Put jumper to Pin 2-3.

HI @adamoutler
please let me ask which temp sensor you use? I’ve only yesterday realized that the command_line sensor many people use, isn’t the only core temp cpu sensor, and system monitor has a sensor too… (been starting at that for ages, and never saw it ,)
these 2 sensors aren’t always in sync though:
Guess that can make a lot of difference around these thresholds.
If you’re not using any of these, but create a dedicated sensor in the add-on, could you please expose that too, like the Fan speed entity. That way we can see what’s going on precisely.
thanks
seeing this regularly after ha core restart:
restarting the add-on brings the entity back
anyone seeing this too?
UPDATE:
apparently this is per design of the author. There is a FR to somehow mitigate this in the repo. For now, we probably can ‘fix’ it using this:
- service: hassio.addon_restart
data:
addon: 7d06b5a0_argon_one_temp
I have that set in a script running after a delayed start_up.

I also notice that the addon starts when the ha core restarts even if you turn off the setting to start on boot…
Thanks for the workaround!
I just install the addom and the fun doesnt work, I used SD card my SSD isn’t installed yet but I think that’s no problem right?. Here is the config:
CorF: C
LowRange: 20
MediumRange: 30
HighRange: 40
QuietProfile: false
Create a Fan Speed entity in Home Assistant: true
Log current temperature every 30 seconds: true
and here is the log. I think I2C its ok but fun doesnt move in log said that its 100% but doesnt work. The files i2c-* are empty

someone have the same problem?
Is the fan running shortly when switching on the Pi? If not, is the connector of the fan attached to the board?

Just thought I’d be obnoxious and say thanks for the add-on. Installation smooth (have faith and follow the instructions), works well. 
Thank you @adamoutler for the add on. It took me a little time with the i2c part but as they say, it is easy once you know how.
Thank you for this add-on. I have installed on Argon M.2 today
But if you ask me how many times I had to reboot the host to get i2c enabled… probably kwazylion - or more. Finally it “clicked”
Quick one: is it possible to see the fan speed in HA? like a sensor or so? I probably did not read all the documentation…
EDIT: I knew I did not read properly All OK.
BTW: I have few RPi4 with this case and with normal Raspberry OS the config from Argon is quite ok and you can set up many levels of the fan speed - here I understand are only 3 - actually 3 is more than enough So thx again for this add-on and your work.
