Recent changes to Project Antec Kuhler 920 Linux Driver/Control

920 seems to disappear, fans go to high.

Long time user, without problems. Running Fedora, since 4, now on 32. Cooler probably 8 years old.
Sometime today, while I was out, computer was running some sed scripts, fans went to HIGH!

Since the cooler ran so well I never even tried to install your software.
Now there is no response to 'lsusb'.
BIOS returns 'N/A' to CPU fan speed (always was 598 - 602 before: Bios gives a 'CPU Fan Error warning below 600 rpm!.

I suspect that the pump electronics have failed. Installing the kuhlerd software does nothing, as the service cannot find the pump.
Any possibility of a fix, or should I go out and find another one? Note, it IS about 8 years old

This works great! Just like the Windows version, without the GUI. Perfect!

hey, glad you found it!

What model do you have? the 920 I assume?

does "kuhlerd" and "kuhler_ctl" exist in the directory where you typed "make"

did you run ./kuhlerd, and then try ./kuhler_ctl?

Hi there,

I am stoked to have found this, but I am having a lot of trouble getting it set up (I am mostly an idiot when I have to compile things).

I extracted the files and simply typed "make"
this dropped a couple of other files in that directory, but I have no idea what to do next. Any assistance you can provide would be greatly appreciated!

INSTALL for systemd

One important modification that occurred to me after sharing this is to change the user running the process from root to another user. I do not know of an elegant way to accomplish this at the moment but I would be remiss as a netizen concerned for the security of my neighbors if I didn't in the least point it out. And it seems better practice to do it any way:

add a user e.g. kuhler and add to kuhler group to the service unit files as follows:

Under [Service]
user=kuhler
group=kuhler
....

And finally, change the owner of /var/local/kuhlerd and kuhler_ctl to kuhler (or whatever username you used / added) ls
and it works.

..confirm everything is hunky dory with ps -aux (and journalctl)

pennies for all

INSTALL for systemd

The included 10-kuhler.rules udev rule to run on BOOTUP does not work with systemd setups and requires syntactical and control flow changes. Specifically, RUN+=/var/local/kuhlerd looks like an older syntax so cannot be parsed well. RUN{program}=/var/local/kuhlerd is the correct syntax as of late but it will not execute as expected. My workaround, which I share to enlighten other fans:

/etc/udev/rules.d/10-kuhler.rules
SUBSYSTEM=="usb", ATTR{idVendor}=="2433", ATTR{idProduct}=="b111", SYMLINK="kuhler", TAG+="systemd"

This will create a device file
/dev/kuhler

It will also cause systemd to recognize the device unit file
dev-kuhler.device

My device unit file:
/etc/systemd/system/dev-kuhler.device :
[Unit]
Description=Kuhler Device Unit
Requires=kuhlerd.service

My service unit file:
/etc/systemd/system/kuhlerd.service
[Unit]
Descripton=Kuhler Daemon
After=kuhler.device
[Service]
Type=forking
ExecStart=/var/local/kuhlerd
RemainAfterExit=yes

My service file (optional) to set fan parameters:
/etc/systemd/system/kuhler_ctl.service
[Unit]
Description=Kuhler Fan Control
After=kuhlerd.service
[Service]
Type=oneshot
ExecStart=/var/local/kuhler_ctl -m1 -s34 -f38
[Install]
WantedBy=kuhlerd.service

]# systemctl enable kuhler_ctl

Tested on LFS 8.1-systemd edition.

Forge ahead!
