ASUS ROG Ryujin III 360 ARGB WHT All-in-one Liquid CPU Cooler with 360mm Radiator. Asetek 8th gen Pump, 3X Magnetic 120mm ARGB Fans (Daisy Chain Design), 3.5” LCD Display. , WHITE

“Finally, a cooler that’s overkill... in the best way.”I’ve built dozens of rigs over the years, and rarely do I find a product that feels both futuristic and practical—but the ROG Ryujin III 360 ARGB Extreme White manages to be both.Out of the box, the packaging feels premium. The hardware speaks for itself—clean lines, gorgeous all-white finish, and a display that’s actually functional. It doesn’t just look cool; it keeps your system cool. I’m running a Ryzen 9 9950X3D, and the VRM fan makes a real difference, shaving 5–7°C off motherboard temps compared to my previous 360mm AIO.Noise-wise, this cooler is impressively quiet. Even under load, the fan noise is a soft, steady whoosh—not a high-pitched whine. During everyday use, it’s barely noticeable, even when airflow ramps up for heavy workloads.My only regret? I played it safe with the 360mm version. In hindsight, I wish I had gone for the 420—the added surface area would have provided even more headroom for an already powerful setup. That said, the 360 delivers.Also: massive props to ASUS for the magnetic daisy-chained fan setup. It makes cable management an actual joy.If you want a cooler that performs, looks incredible, and makes you feel like you’re building five years into the future, this is it.

Pros:Smooth operation, quiet fansMagnetic connectors make cable management a little easierFan RGB are nice and bright, with a full color spectrum. Customizable through Armoury CrateCPU cooler display can display a plethora of information and is customizableKeeps my CPU cool (Noteworthy, I run an open bench setup so this cooler may be overkill but I like the look and the peace of mind)Cons-Not really a hit on the cooler, but syncing the RGB in Armoury Crate does have a learning curve.Overall, I love the cooler and Asus ecosystem. Despite my open test bench setup, the decrease in temps is noticeable and I recommend it.

This cooler does good work. It keeps my 9950X3D well below thermal throttling, even with moderate overclocking/PBO/Curve Optimization. Almost never even gets to 80°. It’s also kinda neat how the VRM fan (which is loud, just like the 8th gen pump) blasts air across the motherboard under load. The LCD screen helps me keep my theme going.

Setting everything up was a breeze. The fans connect magnetically—no tools or screws needed—and even the power hookup uses a magnetic connector. It really cleans up the build by cutting down on visible cables.With ASUS Armoury Crate, linking the LCD display to the motherboard was quick and easy. I was able to upload my own GIFs in under 10 minutes, and now my setup shows off my top game and favorite character for everyone to see.

First CPU cooler:I'm not so irritated about the missing manual, because anyone buying this has likely already built several computers. Still, the fact that the 120mm fans came without hardware was a little irritating.The second-most irritating part is that you can see in the pictures this has clearly been used. Components such as this usually offer a choice: buy this brand-new at full price or pay less for an item with some cosmetic damage. I paid for the former, got more than the latter and for the price of this thing, I expected better.The third, and worst thing of all, is that this "CPU cooler" had a micro-USB cord on it! The same cord that typically charges small devices like cellphones and headphones was attached to the cooler's display instead of a 4-pin! Confused, I looked up the manual online but it showed a 4-pin connector. I contacted ASUS and talked to the heavily-accented tech support. THEY were confused. After verifying the 9-pin USB connector was connected, we went back and forth several times to establish that no, I did NOT have a 4-pin but had a micro-USB instead. Once this difficult concept was established, they offered me top-notch support... by telling me they would create a ticket to escalate it and that I'd be contacted in 24-48 hours. #sarcasmSo, as this was part of the Amazon Prime computer build, which I have yet to be able to put together and use, I contacted Amazon and will just be replacing it through them. For reference, I attached an additional picture showing the replacement (top) next the original (bottom.) Note the 4-pin connector vs the micro-USB. Also, note the chewed up 9-pin USB connector. In addition to that, further evidence (if any was needed) was shown that the original cooler was pre-used.The new radiator had ROG plastic that contoured the shape on both sides whereas the original did not. Finally, as you can see on the CPU mount was shiny and clean when it arrived. The new one had a square of generic thermal compound on it.Second CPU cooler:I had it replaced with an identical model and, this time, I did get a 4-pin connector instead of some ridiculous cable. However, I'm finding it's not doing a very good job of keeping my new system cool. First, I tried to use TPM7950 on my 13900k CPU. I had temperatures spike up to 100C. I looked it up, people sang nothing but praises for the TPM7950, and recommendations were to redo the mounting pressure by loosening and tightening the screws. Temps dropped about 15°C, but when I went to do something as simple as install a game, the temperatures shot up to unfeasible levels again. It was enough to make the display spazz out and continually display "Warning 95°!" even while the computer was off. I had to toggle the power switch on the PSU to get it to stop that. I took off the TPM, applied MX-4 silver compound (I ran out so I used some spare compound), and retried it. Temperatures were a lot better, resting in the low 40s, but when I tried to run that game I mentioned, temperatures again shot up to 100°C. Tomorrow, a much larger syringe of Arctic Silver MX-4 will arrive, and I'll redo the application on the CPU, but this cooler is NOT doing me any favors. I even removed the Noctua fans and added on Silent Wing Pro 4 120mm fans, because they move a lot more air, and yet this cooler is STRUGGLING to keep this CPU from burning itself to a crisp doing the simplest of things. So, that makes me wonder: if I redo the thermal application with high-quality compound, and it STILL wants to melt down like a nuclear power plant, when do I do then? Do I send a SECOND CPU cooler back to Amazon? Do I bark at Asus support to correct the problem? They seemed clueless the last time I talked to them about the first one, so I'm skeptical about how well they'll do with the second. I have what is supposed to be a top-of-the-line system with components that cost thousands of dollars, and it amounts to a very heavy paperweight as I try to figure out how to keep it cool. So far, from Asus and in this one computer build, I've come across these two CPU coolers (one having the wrong cord and the other under suspicion of cooling poorly) and a motherboard that would pop errors when any memory was used in the first two channels. Asus used to be a good brand to me. Now, I'm wondering how many circles they're making as they keep cutting corners. So far, they're 0/3 in this build.Not impressed Asus.Not impressed at all.

Great looking AIO that keeps any CPU nice and cool. Terrible software that ruined it for me and I sent it back. If you are a fan of Asus this thing is a good buy. This is priced as the best AIO on the market and I can't really argue with it...

Been in operation for 6 months now on a core i9 process or that is noted for running hot. Works fabulously. Keeps the CPU temperature in the 35 to 45 C range continuously, with temperatures typically less than 40 C.
