920 seems to disappear, fans go to high.

2020-06-15T02:46:18.374000Z

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!

#6 Install/set up trouble

2018-04-15T23:05:30.472000Z

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!

#5 Kuhler 920 on Fedora 22

2015-08-06T01:54:26.923000Z

Hi!

The driver is pertty generic, it's a source-only package so it should work with most Linux distro's, I even have one confirmed report of OS X working.

Just untar it, and try running "make", you may need "libusb-dev" or some version of that library. The "rpm" command should be able to install it.

The Kuhler hardware is pretty fail-safe, the pumps and fans are always running even if the driver is not installed, so there is little danger of toasting a system.

If you need help, let me know , I will see what I can do. Most of my testing was done on Ubuntu/Mint.

If you do get it working, please let us know, and I'll add it to the supported OS/CPU list.

Also, do you have a V1 or V4 Kuhler?

the USB id's will help. In linux please do "lsusb"

2433:b111 is the V1-V3, while 2433:b200 is the V4 Kuhler.

Kuhler 920 on Fedora 22

2015-08-06T01:49:27.037000Z

Hi there. I posted in discussion under anon by accident before realizing that this would probably get a faster response. I currently am running on win 8.1 with chillcontrol V and want to make sure before I install linux (dual boot, with Linux as my main OS) and make the switch I am wanting to make sure that this driver/control will work on Fedora 22 with a Kuhler 920. Not sure on the version number, but I bought it in 2013 and am running an AMD FX processor. I wanted to know if I need to make any changes to the source, or if the latest should work as is. And then if I do need to make changes, what those changes will need to be. I have looked all over the discussions and the net and have not found any mentions about this working on Fedora. I am hoping that this is still being moderated and checked up on by people. Thank you!

I can read the code with "sudo kill -1 PID":

But even though now I see the correct values in kuhler_ctl:
