ASUS ROG RYUJIN III 360 ARGB about liquidctl

[MiahNelah]

External fan 1 isn't stuck to 1380, it change a little during my tests: on my first test, external fan 1 was as 1350

I said that because I noticed these:

├── External fan duty         73  %
├── External fan 1 speed    1380  rpm

and

├── External fan duty         50  %
├── External fan 1 speed    1380  rpm

Perhaps it just needed time to update. If those work, that's great.

Yes, I run status command less than a second after changing speed, fan need alittle more time to reduce speed.

Either way, AFAIU your AIO works well with liquidctl, and the only thing is that there are three superflous readings for external fans 2, 3 and 4?

That's it, have temperature and global pump+main fan speed is already great! I'll dig more on my side about fans and update this thread if I discover something.

[MiahNelah]

There is, but all 3 fans are combined into one PWM, that's why all three fans are controllable and used as a whole.

[aleksamagicka]

Indeed the same ID as Ryujin II by ID. Support for Ryujin II is in Git, can you try it and see what happens? AFAICS from the docs, Ryujin 3 does not have a separate controller box, so things may be different.

[MiahNelah]

Since Asus Ryujin II 360 support have been merged, I pulled last commit. Here is some test result.

Device is found as Asus Ryujin II 360 as expected.

I can get temperature, settings and speed, which is already awesome !

I tested to change pump speed, and it seems to work:

$ ./liquidctl --serial 377238833430 set pump speed 99
$ ./liquidctl --serial 377238833430 status

Speed change is not only visual, it looks it's correctly applied : fan speed change accordingly. Here is a test with pump speed at 75%, fan are slower than with 100% speed.

$ ./liquidctl --serial 377238833430 set pump speed 75

So, except that device's label is wrong, everything looks good !

[aleksamagicka]

Thanks! What about pump fan and external fans, are they controllable? AFAICS the device does not have connectors for the external fans?

[MiahNelah]

I used Asus Ryujin II 360 docs to get channels name. Everything looks controllable like on Asus Ryujin II 360.

I don't really know why some fans are not displayed. I'm pretty new to Linux and all my fans are not detected at all. I still digging this issue.

[aleksamagicka]

These seem stuck at 1380 (and zeroes) more often than not:

├── External fan 1 speed    1380  rpm
├── External fan 2 speed       0  rpm
├── External fan 3 speed       0  rpm
└── External fan 4 speed       0  rpm

How are external fans connected to the AIO? I can't really discern from the quick guide on ASUS' website.

Do you mean those above or those generally on your system? If the latter, try running sensors if you have lm-sensors installed.

External fan 1 isn't stuck to 1380, it change a little during my tests: on my first test, external fan 1 was as 1350. Other external fans do stuck to 0 however.

From manual, pump is plug to CPU_FAN or AIO_PUMP or W_PUMP pin. External fans are plug to regular FAN 4-pins. I may take a closer look this weekend to I plugged all of this, I may have fucked something.
Can all external fans be controlled like one ?

sensors do not see my PWM fans system-wide. I tried sensors-detect and pwmconfig but without success. However, I do see fans in BIOS, and can control them in PWM mode.

Perhaps it just needed time to update. If those work, that's great.

From manual, pump is plug to CPU_FAN or AIO_PUMP or W_PUMP pin. External fans are plug to regular FAN 4-pins. I may take a closer look this weekend to I plugged all of this, I may have fucked something.

Pump is plugged in probably to silence the BIOS warnings for having no fans? I don't see another reason right now, if it's controlled through USB... Or maybe it's just for power.

Can all external fans be controlled like one ?

Depends on how you connect them, you can use PWM splitter cables and chain them to one PWM output from anywhere.

Either way, AFAIU your AIO works well with liquidctl, and the only thing is that there are three superflous readings for external fans 2, 3 and 4?

[MiahNelah]

I'm the biggest idiot! Of course my device is seen as Asus Ryujin II since IT IS an Asus Ryujin II and not a Ryuijin III !
I'm so sorry for this lost time for nothing, I should have check this before everything.

[aleksamagicka]

Still interesting, doesn't it have a separate controller for the fans?

[aleksamagicka]

Ah, then that's indeed a RYUJIN II.

@jonasmalacofilho, can this be closed as-is, or should I change the title and/or add a label? (I don't see a proper label in the list, though...)

[davija]

I recently purchased an ASUS ROG RYUJIN III 360 (not the ARGB version) and can confirm that it is not currently detected.

This one connects via USB and has a 4-pin header for MB CPU-Fan / AIO header.

I'm willing to help with adding support and testing, I just need to figure out what needs to be done. On initial inspection it appears that the interface is the same as the Ryujin II just different id.

[aleksamagicka]

@davija, this is all you need to do to get liquidctl to see it as a RYUJIN II. Try it out and report back, perhaps it's similar. (If you need help applying the commit/change, I'll give instructions.)
