Thanks alot for sharing this! I just signed up for this.

 

 I'm not actually using Xpenology but rather Openmediavault and the fans seem to kick in to 100% and then ramp down. Your code helped me figure out how to manage the  fans.

 

For reference to anyone stumbling on this thread and wants to port it to OMV:

1.  You need to change where the drives are detected since it's different from DSM. For me it was located in /run/disks

EDIT: These did not exist by default. I've created this directory and just created empty files inside (as root):

mkdir /run/disks
cd /run/disks
touch sda sdb sdc

This far from perfect and if you're a Linux wizard you probably can do something better with regex, e.g.  /dev/sd*[a-z]

 

2. Replace the directory in line 51 (fancontrol.cpp) with the directory containing your drives. For me that was: 

const static char * synostoragedir = "/run/disks";

3. Compile fancontrol.cpp and run with sudo. 

 

 

Tip: You can use a docker gcc image to avoid installing dependencies on OMV/Debian/Ubuntu

Pull the image:

docker pull gcc

Compile fancontrol.cpp (you must be in the same directory)

docker run --rm -v "$PWD":/usr/src/myapp -w /usr/src/myapp gcc gcc -o fancontrol fancontrol.cpp

Make sure run with fancontrol with sudo.

This helped me out tremendously. I'm running this on OMV 5 and it works flawlessly. The only issue I had is that I didn't pay attention to where the /run/disks was supposed to be created at. It's /var/run/disks, and then you create each file with that name.
