This cooler is expensive but it is high quality and beautiful . I love everything about it and it is so easy to install and connect everything . I tried quite a few coolers before this one and to be honest i like this one the most . Im going to keep it until it breaks or i build a new rig in few or what ever years . The reason i switched to this cooler is that i have everything else in my pc from ROG and want it to match it but it turned out i have the best temps with this cooler . 32C on idle and 45C when gaming . Also love that i cat monitor the temps of the cpu and gpu while using pc . I switched to this cooler from DeepCool Mistique 360mm and the temps are 5 to 10 Celsius lower with ASUS ROG Ryujin 360mm . Also the software is much easier to deal with than with any other cooler . The best thing about having the complete Asus ROG parts is that i dont need to connect any rgb wires and all works for some reason , not sure why ? I would guess it goes through the mobo . I mean the cooler is almost the twice the price than most others but im ok with it because is worth it . It is hard to decide what cooler to buy by looking the reviews because its not the same for everyone . In my case i would say it is perfect because i have all Asus ROG parts and there is no software conflict of any kind so it works perfect in my build . Btw , I have my 14700K oc to 5.6Ghz and the temps are just awesome . Also , ASUS - ROG MAXIMUS Z790 HERO (Socket LGA 1700) USB 3.2 Intel Motherboard ASUS - ROG Strix NVIDIA GeForce RTX 4080 SUPER Overclock 16GB ROG Thor 1200W Platinum II 1200 Watt Fully Modular Power Supply 80+ Platinum If the money is not the issue get it , if it is than you wont even look at it i guess .

The ASUS ROG Ryujin III 360 is hands down one of the best AIO coolers I’ve used! The Noctua Industrial PPC fans deliver excellent airflow while staying surprisingly quiet, and the cooling performance is top-tier, keeping my high-end CPU at low temps even under heavy loads. The 3.5-inch OLED display is a standout feature—it looks incredible and lets me display system stats or custom animations. The added VRM cooling fan is a nice touch, keeping motherboard components cooler. Setup was straightforward, and the build quality is top-notch. My only minor gripe is that Armoury Crate software can be a bit buggy, but once set up, everything works great. If you want elite cooling with premium aesthetics, this is the AIO to get! Highly recommended for high-performance bu

“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.

ASUS never disappoints with their ROG line of hardware. Powerful AIO with a 240mm radiator and double Noctua 120mm fans combo has been a beast in my computer. Screen on the pump is clear and bright. Displays anything you can think of and in HD quality. Easy to install and the performance is top notch. Haven’t had any issues since installation.

The cooler is large, but thats expected. It comes with everything necessary to install including the fans. My CPU is around 36c at idle with fan speeds low - around 400 rpm. At full load, CPU is around 75c and fans around 1200 rpm. The screen is a decent size compared to others. The ASUS Armoury Crate software makes it easy to manage and customize the display but is limited. However, the optional AIDA64 Extreme software is makes it highly customizable. Just takes a bit of a learning curve. Overall, it was an okay upgrade from my previous cooler, the Deepcool LT720.

Ran this AIO with a 7950X3D for about 3 months and it kept temps low even under full load. The LCD screen is super clean, I’ve got a custom GIF on mine, and the ARGB fans look great without being too loud. Install was smooth, and the daisy-chain setup really cuts down on cable mess. Pricey, but totally worth it for a build like this.
