Asus Ryujin 240mm

[ptruongy787]

Just out of curiousity, and I am aware that everyone runs different specs etc but what sorta temps are you guys getting with the Ryujin on idle and load?

[ptruongy787]

im running a 3800x and my idle temps are around 40-45 degrees, gaming is around 60-65 and using Cinebench its about 80ish. I know and understand everyone runs different setups, but would really like to know are my temps normal for the 240 Ryujin?

Be aware that these Asus water coolers (Ryo and Ryujin) do not react to the temperature of your CPU cores at all. They can get very hot without so much as a single step up of the cooling because this cooler, and Asus motherboards only respond to the temperature of the motherboard near the CPU, and not the cores. This is a design flaw that supports the view that noise your fans make is more important than the health of your CPU. Hence, if you are not careful, you can brick your CPU.

This is completely false. *Both my pump speed and my radiator fan speed are controlled by my reported CPU temps. *They rise and fall with CPU temperature. In addition, should I choose, I can set my fans and radiator pump speed to rise and fall with another temperature parameter such as PCH temperature or motherboard system temperature.*

If you are referring to how the CPU temperatures are reported, there are many opinions on this. *I prefer a smoother extrapolated temperature that moves quickly but steadily rather than a raw core temperature that jump and bounce around with a simple task such as opening the Internet browser. * Any fans or pumps connected to these types of CPU *reported temperatures jump and surge audibly and are very distracting. Others may have a different opinion on this. But from my testing of reported CPU temperature and actual core temperature using a different program, I find that both *temperatures move together consistently. *The extrapolated temperature moves smoothly while the cooler temp jumps around drastically. *as the actual core temperatures do reach higher levels, so does the extrapolated CPU temperature that the motherboard reports.*

I did a new build with the ROG Hero XI and the Ryujin 240. The fan in the pump constantly surges to max speed and then back down every few seconds. Cannot seem to control the speed of that internal fan. Fan Expert handles the AIO pump, the Radiator Fans and of course the Chassis fans, but gives no control over the internal fan on the pump. It's driving me nuts!!!! Anyone have a solution.

After doing several chats with Asus they issued an RMA saying it's a hardware problem. I have my doubts. I think its software or software conflict. I just uninstalled Armory, Aura, and Ryujin and after rebooting, the pump fan runs continuously at high speed. Noisy, but not as irritating as the constant surges. I'll send it out for the repair, but I doubt if I will reinstall it when it comes back. Too many hours wasted already.

Before I uninstalled the above apps. https://www.youtube.com/watch?v=94MWdjH2iXk

Well, I don't know what I'm doing wrong, but when I installed the latest BIOS for my motherboard, I discovered a few issues. One is that the fans and Ryujin in my rig did nothing to counter high temperatures of CPU cores. The Ryujin temperature reported on the face of the Ryujin as the CPU temperature was about 30 degrees cooler than the CPU cores (read that twice if you dont get it) and neither the fans nor the water cooler did anything to counter this. If you don't believe me, you can watch this reviewer at about 15 minutes in (the CPU temperature as Asus reports and responds to is really according to a probe near the CPU and NOT the CPU itself). Like I said, the temperature Asus stuff is monitoring is not the CPU temperature even though you would think so. Hence, your CPU cores can get extremely hot without the system responding to them. And I have witnessed this flaw firsthand.

Honestly, my Rampage VI Extreme Omega and Ryujin have been a big disappointment in this sense and other senses. From day one I have had loads of software problems in this system and have since simply let this computer collect dust and have been using a different system with a Kraken 62, which in my view is way cheaper and, at least on the software side, far superior (for example by reporting the coolant temperature with the software and not some temperature it calls the CPU temperature--which it only resembles).

Don't get me wrong though, the hardware is top notch. What I don't get is why the company seems to blatantly botch the software regularly.

So I replaced the Ryujin 240 with a CORSAIR - Hydro Series H115i RGB and now the system is quiet as a mouse and cool as a cucumber.

FWIW, and anyone that stumbles upon the thread as I did....

This is a conflict between the AI Suite/Motherboard fan controller (FanXpert) and the Ryujin software in Armory Crate. Mine was doing the exact same thing. I ended up uninstalling AI suite and disabling FanXpert in BIOS. The Ryujin is now entirely under the control of Armory Crate.
