Hddtemp provides no reading, fan control goes to max

1

Hi

hddtemp provides no reading for my WD Red Plus (8 TB, 3.5", CMR):

fips@eon:~ $ sudo hddtemp /dev/sdb1
/dev/sdb1: Pinas sata:  drive supported, but it doesn't have a temperature sensor.

It looks like argoned does not like that and cranks up the fan. Anything I can do here?

Running a Pi 4 B 8GB with Raspberry OS Bullseye 64bit.

Thx!

If you are using the scripts as provided by argon40, i.e. you ran the following command:

curl https://download.argon40.com/argoneon.sh | bash

The code will automatically set the fan speed to 25% if a value of 0 is provided. You can fix this one of two ways:

  1. edit /etc/argononed.py, find the function get_fanspeed, and comment out the following:
         if fancfg < 25:
             return 25

To comment out lines in python use the ‘#’ character…

#         if fancfg < 25:
#            return 25
  1. Uninstall and download from
curl -L https://raw.githubusercontent.com/JeffCurless/argoneon/main/argoneon.sh | bash

I know that hddtemp will provide temperature readings for the Western Digital Red Plus, because I’ve a Western Digital Red Plus in my Eon as well.

However, because it’s sat on the other side of a USB-SATA bridge you need to address it differently. If you take a shufti at my fork of the Python scripts, you’ll see you need to prefix the device with sata: first. You also need to address the drive, not the partition.

So instead of:

sudo hddtemp /dev/sdb1

you need:

sudo hddtemp sata:/dev/sdb

Which will work fine. However, you should get into the habit of using /dev/disk/by-id or /dev/disk/by-uuid instead, 'cos then they’re guaranteed to be the same drive each time you reboot.

That fixed it. Thank you very much for the quick reply, the noise was driving me nuts :slightly_smiling_face:

Nice, thank you @ghalfacree. Indeed, with the sata: prefix I do get a temperature reading.
