Question ROG Ryujin 360 - minireview

[FlanK3r]

History of CPU cooling is longride way. From basic coolers to extreme cooling as example LN2. We can remember 20 years ago...Yes, everything looks like stock boxed cooler But different was the cooler for AMD Thunderbird CPUs.


Cooling systems were evolved, first home liquid cooling and worldwides forums were full of users. They shared about all information how to do home setups, how tweak the processors etc. etc. It is history. Today people want to have cooling system ready to use with good design, easy installation and silent working.
At the end of 90s started also extreme overclocking. In Japan guys cooled PC with dry ice or liquid nitrogen.




About 10 years ago there was big market with aircooler with high cooling performance and low noise. In this age came first AIO Coolers. Im thinking, one of the first was Corsair H50 and Antec Kuhler series. This Antec (model 920) was very strong, but with max RPM really noisy. Later tthis cooler was as revision for AMD Bulldozer bundle (CPU+FX AIO cooler).


Do you know, Asus had Air coolers many years ago? Do you know Asus Triton or Asus Silent Knight? So this company has some experience with cooling and in 2018 they are selling AIO coolers. There is ROG Ryuo and higher model ROG Ryujin. Ryuo exists in 120 a 240 mm version of radiators. Ryujin has 240 and 360 models. But we will focused on highest ROG Ryujin 360 today.


1. Desription and Ryujin theory

Noctua fans, cool design, sleeved tubes, adressable RGB LED and OLED display and inside the embedded fan. Thats it!


Mentioned before - Noctua Industrial fans




This is what I like. Emedded small fan to cools VRM of the motherboard or first M2 slot. This is special y necessarily for Z390 with 9900K OC combination or X299 or X399 CPUs.



OLED display and some functions on it. U know propably Linus face on display at Computex time



And AURA Sync support via LiveDash app

2. packaging



On the box, in ROG style, front part shows important information about Noctua coolers and on the back side of box are features like OLED display 1.77", small "VRM" fan on CPU block and about AURA Sync.


Inside the box are three Noctua Industrial fans about size 120x120x25mm. Those fans working in range 450-2000 rpm and cooling performance is up to 122CFM. You propably know, Noctua fans are really effective in performance/quiet ratio. Specs says only 29.7 dB!!


Fans have braided cable with 4-pin PWM connector. On the photo you can see noise reduction rubber pads.


Socket reductions and many screws for installation. The cooler is from factory ready for LGA115X motherboards. But you cand find in accessories AM4 bracket and universaly backplate. For TR4 you need change the bracket which is inside the box of TR4 CPU (Threadrippers).


Plastic design cover over the CPU pump. You can see plastic "window" on the bottom corner for OLED display informations or animations.


Radiator is classic 360 alluminium material, thats mean for 3x 120mm fans in one row. Real lenght of radiator is over 390mm, widht 121mm and thickness is 27mm.
Rubber tubes have about 430mm lenght including screws (390mm without it). This is more than enough for most of cases.




CPU integrated block contact is a copper. The side view on the block show the small fan inside for VRM cooling. The size of fan there is 60mm. On the top of integrated block is OLED display.
Connectors in my hands including 2x PWM female connectors, SATA cable for power, USB 2.0 connector and 4-pin PWM for the pump.

3. AIO installation process

Zhe installation process is easy. From stock is preinstalled cooler for Intel LGA type of platform. For AMD AM4 we have reduction in the package. For TR4 socket we can use Asetek reduction from CPU package. Then we will use screws for hold the cooler.


First remove the reduction, use light push and rotate to remove the stock reduction. After you can add new one from CPU package (TR4)


Now you screws up directly to the motherboard - no backplate needed for TR4 socket.



In the finish looks like that...


In the end I set up the Noctua fans on radiator.

4.SOFTWARE and AURA
After start the PC has ROG Ryujin own small storage for firmware (on the screen). Do not remove this storage or do not format it.


Fan Xpert is part of Ai Suite software (Asus motherboards). I recommend download alst version from website of MB product. And is it good way to tweak your cooling depends on temps and rpms.







LiveDash app is for tweaking your OLED display and set RGB colors or synchronization AURA effects. You have choice between hardware monitoring informations or custom gif animations or custom banner or simply some yours photos. Few examples lower.

5. TEST SYSTEM

AMD Ryzen Threadripper 1950X (stock i OC nastavení)
ROG zenith Extreme
ROG Ryujin 360
ROG Strix GTX 1050 O4G
4x 8GB HyperX Predator@3200 MHz
Corsair AX1200
Windows 10 Home 64bit



software for testing:
CinebenchR15, AIDA 64 stress test, hwinfo, Sound meter - phone app.



noise level I tested on open case (read the benchtable) from 20-30cm distance. In table are examples of noise (in Czech language, 10db=scour the leaves on tree, 20dB=calm in nature, 30dB = very quiet room, 40dB = normal noise background, 50 dB =normal conversation )

6. TEST RESULTS ON CPU STOCK SETTINGS
Idle

The cooler is in CPU idle in Windows very quiet, only about 37 dB, sometimes are Noctua fans spinning off and the highest noise source was PSU and chokes inside...

Load on CPU stock settings
First time I run CinebenchR15, max temps on CPU were 60 C.


After I ran AIDA stress test (including AVX) After the temps was the same, I measured noise also. It was about 46dB average, keep in mind, it is still open case and very close distance (20-30cm) - thats not typical customer situation. And must say, 46 dB is still solid quiet on this distance. The max temps were up to 70 C. For so big boy as Threadripper is it good result.



Max fans+pump speed

Noctuas fans are still very solid quiet, but pump is a little noisy. You can see result is now about 56 dB

7.CPU OVERCLOCKED - RESULTS
Ussually first gen of Threadrippers can hold between 3.9 GHz up to 4.1 GHz, depends on quality of chip and cooling methods. My sample is solid, I tested it one year before.

With LLC3 and 1.275Vcore I got final frequency on chip 3950 MHz. I was close to 3975 MHz, but after some time I got error. Average temperature was 71 C on chip.


I left fans on the maximum for to be save for highest CPU stable frequency...So again 56 dB

I tried also Cinebench on maximum. Up to 4050 MHz on all 16 cores and 32 threads.





If I compared full cover IHS AIO cooler with ROG Ryujin 360, there is some difference. Still, TR4 coolers are more specialized and some part of heat can be on corners of IHS (there are not CCX, but some heat from it). So basically temps on die are a little lower and thats mean a little higher OC. But AIO TR4 are only for TR4 platform and can not use it for another else. ROG ryujin is more multipurpose.

8.CONCLUSION
The price is not the best, but...I like design of the cooler, OLED display and also small cooler to cooling the VRM. Thats very good idea. Of course I can not forget on Noctua Industrial series fans. These are really quiet. Manufactory process is on high level - classic Asus. I like also software part to tweak the pump+fans in FanXpert. The main HW statistic information you can have on your OLED display. Why not. The cooler is really quiet , specially in idle. Of course with high overlcocking the noise will be a bit higher, specially on platfrom, where the CPU has close to 300W package But on "standard" CPUs it will be different story (ussually around 180-200W after OC).
I see disadvantage in you con not refill the liquid or adding next hardware to the liquid cooling circuit as example GPU. Alphacool Eisbaer has this feature. But it is first ROG AIO cooler, so maybe in next version in future? Anyway I can recommend you this cooler if you are ROG fan or if you want quiet and good performance AIO cooler with active VRM cooling and wow effect OLED display

Handling a 1950x is no simple task. Has anyone reviewed this AiO on a 9900k yet?

 

[FlanK3r]

Im not sure, but Il switch it soon and can do few retests on my 9900K also

 

[DrMrLordX]

Sounds good, thanks.

 

[FlanK3r]

There is part with i9-9900K and ROG Ryujin 360. On paper, TDP of 9900K is 95W, but is far far away from reallity. CPU power package is in practice around the 160W (BIOS on auto+XMP), This huge numbers are not often to see, but sometimes u need really test your stability properly . For Intel CPUs are best stress still PRIME95. I used version without AVX stress test - in BIOS I have negative offset 2 bins. U can tests classic blend test with random stress test of CPU/RAM/IMC or manually FFT hardcore test up to 12K size.
PS: In my room was about 19C


I put ROG Ryujin from Threadripper baby to Maximus XI Gene and i9-9900K ES (not winner of sillicon lotery :-D )


No conflict here..., Maximus XI Gene has DIMM slots close to CPU


I am interested for PRIME (test blend test and FFT small)

On stock settings I got several good numbers.
[highlight=yellow]Temps are between 61 to 68C[/highlight]

With FFT 8K (and higher) you can see "real" power consumption of CPU HWInfo. As you can see there is it up to 168W on CPU power package. This is not really 95W CPU .


Conclusion 1: ROG Ryujin can cool down your 165W soldered CPU very well, temepratures are under 70 C.

And what about overclocking? We can expect the power package on CPU will be much higher. Before that, you have to do some BIOS steps. First, all power package limitation change from AUTO to maximus value. Also set the CPU core/cache current limit on max and in digital control settings of VRM set CPU Current capability to 140% or more.
My experience is set the Vcore upper limit on 1.35V for 24/7, but be sure for high temperatures in load. In Cinebench around 80-88C (depends on your room temperatures)! But better start begins with 1.22-1.25 vcore and thats your startpoint.
On my side, the CPU sample is not king of overlcocking. I tested maybe 20 Skylakes/Kabylakes/Coffee/Cofee refresh processors and this one is second worst in OC headroom . I used really high 1.375V and LLC8 for "true" vcore Whyt true? Just look at this Asus video:

Max stable OC on my side on all cores was 4838 MHz


PRIME 95, FFT=8K and temps were between 89-94C

Software CPU power package doesnt work now, so I used classic power usage meter

370W for CPU load and others components in idle! Thats more than Threadripper 1950X or more than i9-7900X.


For fun I tried earlier FFT=12K test with 1.35V and 4900 MHz for short time (before I got BSOD after few minutes) Crazy temps 93-104 C

 

[DrMrLordX]

So add one more AiO to the list that can cool a 9900k. Good to know, thanks!

Its not cheap, but performance is good and I like outside design + animations (lol, my Bad Spencer animation on top )
